Good day, thank you for the movie. It is a big relief to watch such STEM supporting lectures in this times. Optics is not may domain (physics either) but I'm happy that you belive in equations and the mind works as a basis of human kind. Thx. I wish I know you personally. Best regards. Post Scriptum: I have 15 years to retirement so I'm really try not loose my faith.
Nice introduction to catadioptric stuff. We were given a purely mathematical introduction, and I couldn't often "see" the shapes the math created. You have done for this topic what Oliver Heavyside did for Maxwell's equations. Good presentation.
I grew up just down the hill from an HP Labs facility in Palo Alto. I used to ride my bike past it often. Don't know if this is the same lab you worked at back in the day but I remember it well! Good old Page Mill Rd.!
Awesome! Was trying to determine how to get more light into my east facing window. It can't absorb from the back and I'm restricted in build space, but the solving for an angled blade detector should be pretty close.
Hi , thanks for the video! Also small question . Have you heard on the trion-re shape ? It seems it has some very strange optic properties , was wondering if you can take a look at research of Michael Evans , and explaine what is going on inside the crystal shape. Thanks in advance. :)
CPC are now a built in non-sequential object in Zemax. I was looking to understand this rectangular CPC object in Zemax better and found your video :)@@IMSAIGuy
Sir, could you please add a series on Intrduction to Optics and Coatings? Today's electronics make use of both visual and infared sensors a basic understanding would be very helpful. Thank you
thank you for the video, I have a question, i am interested in ray collimation of a defused light source, and I want it to be really well collimised, like a laser; and more imprtantly, only with reflectors and not with lenses any suggestion? is it even possible? can you suggest some books, papers or even key words to search about it? my background is not in optics but iam enthusiastic about this field, so even basic guidances are huge help to me.
@@hanhchu6233I don't have the time sorry. If you really need to understand this then derive the equations for yourself. All the math is there. it is simply two parabola halfs, each off axis and tilted.
Fascinating! I thought guys like you never retired, just kept on in the lab and published now and then. While you're on the subject of light reflection, could you do a talk on foot candles, (???), I think. Possibly how it changes with incadesent lighting verses LED. What is the best kind of lighting? Great info on this video, thanks.
String method is just what i was looking for.

I worked at 640 Page Mill doing LEDs then at 1501 Page Mill at the labs
Amazing video man, thanks for posting
Fascinating stuff. I wish you could have demonstrated the string method, or explained it a little better.
Someone should make a parametric CPC CAD design, based on the size and shape of the collector, and the acceptance angle.
100% agree with you, add truncation too!
I second that

Thank you sir for the explanation
Do you have a MATLAB model for solar concentrators?Parabolic Trough Collector
No, when I was working I used cad programs like Zemax or Light Tools

no it is not possible. the law of physics you need to know is called etendue.
Good Day! Just wanna ask if that programmed excel still exists to this date. It's gonna be a big help for our thesis prototype

@@IMSAIGuy thank you!!
Thanks :). This will be fun to play around with. @@IMSAIGuy
Are these the same as Involute curves?
no
Can you do a follow up of cpc dish concentrator
not sure what you mean by dish.

I'm sure that one day you will get to the point but I have not got the time to wait, goodbye.
Please post your excel calculations so that I can follow them.

@@IMSAIGuy Thanks for the spreadsheet. What are the definitions for qo, qi, QR, (qo-qi)/2, (qo+qi)/2, and the trigonometric relations between them?

@@IMSAIGuy Is Q at the center of the radius of curvature or at the parabola focii?
MOAR OPTICS 😁🤣
Hi
can you help me please
