The mystery 4 wire part (at 6:20) by the transistor looks like a 4 wire temperture sensor, probably for compensation. Wrapping foil back over the top of is reccomended for cryo sensors and should increase accuracy at other temperatures too. The additional smaller sensor areas in the sensor package might be for offset compensation of the case temperature, functioning as blind pixels that are subtracted from the quadrant measurements to remove the thermal dependent offset.

My guess is we're seeing something similar to a Wheatstone bridge measured on all 4 resistors with a big diode in center. In other words the light comes at an angle, is filtered to reject the unneeded part, and passes trough that round filter window, shining on part of the semiconductor inducing a voltage. The Wheatstone circuit will tell which part was illuminated, hence where the missile is coming from. The micro controller interprets the data and sends a 2D bearing (0-360 degree) to the control unit. If I were the enemy all I'd want to know is the characteristics of that filter.
Very interesting. The optics look like an ultra-wide lens for large field coverage. The PSD surface is quite heavily distorted - I'm guessing that's for correcting both the distortion of the optics and the position non-linearity of the device itself.

It looks like the ring around the back of the IR sensor (with the black wire at each end, and a yellow wire about 2-3cm up from each end) is some kind of RF antenna. I suspect that it inducts a signal into the short wires on the other side of the ceramic board, and whatever reactive change in the sensor material - due to light from the environment - causes a phase shift in the signal that returns. The return paths are the 4 capacitors that are attached to the back of each quadrant, which block DC voltage from the bus (the resistors that are coming from that one line to all the connectors). I'm curious if the goofy wire coils and heavy (brass?) studs that go through the board are to keep the connection resistance as low as possible, so that it doesn't cause thermal 'ghosts'. It's an awful lot of expensive hardware to give the parameters: "Is a hotspot getting closer" and "Is a hotspot coming or going". It seems very easy to trick and defeat. I sure hope that tech this abhorrently outdated is not still being used; especially with only 2 stages of photo-multiplier plates. Meanwhile, in the '91 gulf war, relic battleships were detecting oil well fires (presumably on land) as missile launches (or alternately, they were anti-ship missiles... depending on which of the same-source stories you want to believe), and firing multi-million-dollar countermeasures in a desperate self defense, which triggered other ships to detect the decoys as threats, resulting in automated bullet-hosing of the decoys and the ships that launched them. Now THAT'S a high-dollar military budget in action, when you expend your munitions stores "just in case", while lesser militaries can't even detect those non-threats to misidentify them.

What year is this sensor from? Looks to be fairly old. Always interesting to see how they packaged electronics like this, especially when trying to remain concise.

It's so simple and smart ! It's based on a solar-blind UV image intensifier tube and a PSD. SB UV emitted by missile booster is detection by the UV tube and its position is measured by the PSD. The PSD should be made by selenium thin film ?
@@AlexanderGee the most expensive should be the solar blind bandpass filter ! The UV tube is sensitive to visible light too, so you have to filter out these photons in order to detect only solar blind UV signals which are emitted by missile booster at launch stage.

English Translation. Thank you @kardanium An optical lens of a special configuration focuses the incoming beam to a small point on the surface of the detector. Depending on the angle of the incoming beam in relation to the lens, a point will be formed on one or another part of the detector. Further, its location on the detector is calculated by the ratio of resistances between all detector outputs. The missile itself, receiving data from its gyroscope and from this homing head, calculates the location of the illuminated target relative to itself. After that, it calculates course errors and correction parameters and control signals to the rudder servos.
@@idopshik Да, я писал комментарий во время просмотра. Потом уже понял, что это детектор предупреждения о ракетной атаке. Но основной принцип работы с датчиком все равно остаётся прежним. Результирующий сигнал просто используется для отображения стороны, с которой летит ракета.
I guess it's basically a wide-angle lens with a filter and a position sensitive detector behind it. The shape of the detector probably somehow compensates for lens effects. The filter is probably sensitive to a thermal signature that's emitted by starting missiles. The position sensitive detector helps to identify the direction and course of the missile, maybe to help blind it with a laser. In addition to the specific infrared range that it's sensitive too, it's probably also fairly selective in the time domain, ignoring fires etc. And only reacting to sudden flashes of IR.
"The position sensitive detector helps to identify the direction and course of the missile, maybe to help blind it with a laser." "And only reacting to sudden flashes of IR." If I now understood correctly, those are countering each others. It can't be reacting to only sudden flashes of IR spectrum, if it as well can track the IR spectrum missile that's nose heats up by high speed even after the missile plume is gone after rocket motor shutoff. The Russian L-370 Vitebsk is system that uses four sensors similar to this to detect and track the IR signatures, the detection sensitivity is high enough to detect a SAM launch even from 200 km, and MANPADS size launch well past 10 km, but it will track and symbolize these launches only at 6-8 km ranges when it is considered a threat. So the system detects the launch, track the missile and warns the pilot when the missile is calculated by its trajectory to be a threat to aircraft. And then based to knowledge of launch range, missile time the system will time the release of chaff/flare at proper close range and then use IR lamp/laser turrets to fire a beam (IIRC about 2.5 degree cone) on the missile seeker to blind it, and the turret has as well a RF jammer to jam the SARH/ARH missiles seekers. The older system has only the fisheye lens to detect the short periods of flashes, that comes from launching a missile. As well when firing a cannon or explosion. So such old system gets triggered all the time and they can't track the threats so they don't know where missile is coming or what, and then reacts to them instantly. So if pilot has automatic flare On, the system will trigger flares release every time when a friendly tank at ground fire cannon or wingman launches rockets or missile. The triangulation of the threat can be done with two sensors, so you know the location that way.
If it says "surface may get hot" this could indicate it features heat pump cooling. Once you turn such a system off, the cold side will eventually experience a temperature spike. The average latent heat in the cooling loop is often high, and once you power down the pump, you get that heat back into the cold side. It's less of a problem in boiling-coolant systems like refrigerators, which is why your home freezer doesn't have an isolation valve. Wold be interesting to see the sensor's mounting, if it does in fact feature the plumbing you'd expect for external adiabatic cooling. One factor speaking for this is when you filmed down into the housing. At the back, you saw a grey pad. This pad looked similar to a thermal pad of unknown composition, pressed against the capacitors. This, in turn, could potentially indicate that it is indeed a simple lens & IR detector set to detect the incandescent hot microparticles in the exhaust plume of a missile's booster engine. Since jet engines don't have many microparticles, even though they can get to similar temperatures (though not quite the same), jet engines don't glow anywhere near as intensely in IR as a solid rocket booster does. This could perhaps allow it to discriminate between airbreathers and solid propellant. (Jet or rocket.) This may mean it could not discriminate between rockets and flares. If it can't discriminate, this would mean that a chasing aircraft launching one of its flares would cause this sensor to misinterpret that as a missile launch. The target aircraft would then launch multiple flares. This could potentially allow an attacking aircraft to deplete the target's flare magazine prior to launching an actual IR missile. But on the other hand, a flare is surprisingly small, and a missile's booster motor is absolutely MASSIVE. So perhaps there is enough of a difference in intensity to allow for discrimination between flares and rockets, I don't know. Hypothesis: If what you thought was an LCD aperture is indeed an LCD aperture, this could allow for rapid sampling of thermal output in watts, not adjusted for distance. Simply block the sensor until baseline reading. Then un-blind the sensor, and measure how quickly it reaches "detection". This will correspond to a given wattage at a given distance, and could allow for plotting a curve of the missile's thermal output. This could hypothetically allow the sensor to differentiate between boost phase (sudden, high output followed by rapid drop) and cruise (constant output slowly increasing as the distance decreases). This in turn perhaps allow the system to tell if a second weapon is launched, requiring additional countermeasures to achieve probable soft kill.
@@lelabodemichel5162 OK. I'm still curious how the system would react to blackbody radiation in the 1-3000 K range. A common incandescent lightbulb does reach those temperatures, and at close range, should emulate the output of a rocket motor at long range. I get if you don't want to test it, though.
thanks for very exclusive review. Is this thing pretty old right ? because I see very brutal microchips, elements and wires. Currently it might be 2-3 times more compact in term of schematics.
Nope, because of the optics section you cannot make smaller IR MWS. By the way nowadays, ceramic chips, passives and rigid flex PCBs are same/similar to this unit.

This, when the technician assigned to learn everything from captured hardware decides to make TH-cam videos
Clarify the use of the thermal battery, and safety from its danger.** What are the risks of reversing the polarity of a thermal battery?
thanks for very exclusive review. Is this thing pretty old right ? because I see very brutal microchips, elements and wires. Currently it might be 2-3 times more compact in term of schematics.
Nope, because of the optics section you cannot make smaller IR MWS. By the way nowadays, ceramic chips, passives and rigid flex PCBs are same/similar to this unit.
never know if hes talking english or french
El sensor parece un LDR
QUAL O ANO DE FABRICAÇÃO?
Очень интересный набор систем и устройств. Еще б был разбор как это все железно работает. Но судя по мозгам это оч интелеатуальный фотоумножитель. Пожалуй стоимостью в десяток штук баксов. Если не больше.
9:06 i see that it has been made on litography, i wonder HOW they discovered this tech?! this is certainly alien bluprints.
It is a rare conten on youtube...that i have ever seen...that is be a secret some country..
Le labo de Michel спасибо
All this beautiful technology for killing others
or protecting?
@@resetcoderprotecting by killing
damn, 3rd world countries don't need to spy this days
I bet it’s not going to work anymore…
Похоже на тепловизор
Что это?
old time sersorte
дуже схоже на тепловізійний датчик.
Не похоже вообще, у тепловизора используют германиевую линзу. а в конце должна быть матрица. А это больше похоже на какойто диод
Sensors for this light band contain VERY DANGEROUS chemicals. Do not touch IR devices with bare hands!!
This one is likely a sapphire, which is absolutely safe. Other materials, like ZnSe is OK also, I had no any problems cutting or polishing it. However, manufacturing ZnSe in bulk is another story.
Tech needs to be constantly updated and improved or it and the company around it becomes obsolete. The design of this board is _ancient_. If this is an average indication of Northrop Grumman tech then this is looking like sweet sweet opportunity.

У вас много различной электроники с содержанием золота на продажу в украину ?) Я мог бы покупать у вас испорченные компоненты в больших обьемах для добычи из них драгоценных металлов есть знакомые люди котрые могут привезти из франции в украину для переработки. Как с вами связаться обсудить данный вопрос ?
I don’t care about gold, I hate people who recovers gold from these precious electronics.
@@lelabodemichel5162 неисправные детали использовать по назначению уже не получится ! Вот я и перерабатываю то что сломано .
Даже автор согласен с тем что б вас послать.. афинажникам не место в электронике.
Всегда был в шоке от того, как они просто корёжат дорогую технику.
@@idopshik господа одно дело корежить приборы которые можно использовать а другое дело корежить детали от ракет которые кроме смерти ничего принести не могут и от агрегатов которые в нынешнее время уже не актуальны ,я на личном примере убедился когда продавал осциллограф с1-64 по стоимости драг металлов в нем и никто абсолютно из радиолюбителей не проявил никакого интереса к данному прибору ! Все уважающие себя электронщики давно перешли на более современные и малогабаритные образцы . Хранить как достояние общественности я не собираюсь потому как общественности вообще насрать на эти приборы и на то чтобы их сохранить , поэтому господа с уважением конечно к вашим талантам в электронике, но хватит здесь мудеть какие вы все правильные и достойные ! Все выживают как могут умеют и считают правильным .
C'est dommage d'avoir quelqu'un de compétent en France qui aborde ces passionnants sujets en anglais.
Hello, le pb c'est que le public intéressés est minime, alors si on se limite aux Français ça fera peu d'audience. Et puis faire de l'électronique sans Anglais de nos jours. NoWay. Une excellente occasion d'apprendre, c'est de l'Anglais facile :)
И шо это за поебень ? Ниодного слова по русски....чёта разобрал-сломал и выбросил в мусорку,не рассказав что это и хде применяется(применимо) и чем может помочь😂😊
Тебе ни чем не может помочь.. скудоумие заразно.
Говорит , микроволновка сломалась. Выковыривает драгметалы.
this is old militari device?
Yes and no. Northrup is currently marketing it for use on commercial planes. So, it'd old enough that the military likely has something newer/better and doesn't care and it's still good enough for Northrup to sell publicly.
@@randomman057 I recently drove through the fields where I live and collected electronic payments from missiles that were shot down. There are components from 1986, but somehow it flies. The crazy USSR could not make a normal car, but the missiles hit first of all. There's a lot of precious metal in these components.
