Sir, very good explanation, congratulations 👏 Sir I am a school teacher pursuing part time PhD, recently I took HRTEM of samples, I will calculate d spacing with the help of this video. Thank you sir 🙏
Thank you for your useful video sir. Personally, I have learned lot of analysing tools for material characterization from you. Now, it's continuing through TH-cam too...... Congratulations sir....
Thank you sir. I used to analyse d spacing using Gatan Digital Micrograph software. But after watching this video, I find it better way to determine it.
Sir, Thank you very much. your voice and teching level is very simple. I am easily calculating my value using this video. once again thank you so much sir.
Thank you for great lecture professor. I have one question though. When you choose a spot from the FFT, if you choose not the brightest one but another, you said the angle will be different. In that case only angle is different and the lattice spacing is same? or the differed angle means that the changed of (hkl) ?
thank you very much sir....this video is extremely useful and thanks for using a free software. it will be very much helpful if u could explain the process like what is fast fourier transformation eventhough its out of the scope. please continue this work.......tqq
Thank you very much sir very useful video. I want to know we got only one d space value. what to do next with this value? For hkl indexing what we can do? i don't have saed pattern.
You might have miseed a step in which you have to select a point in fft image and mask it with a round and white color... Please watch the video again madam.
@@prantisutar5363 I got the same situation then I press the Backspace button after creating the oval, then it works. Maybe also should pay attention to what kind of color picker (in the video is front-white, back-white) is using.
Dear sir, Thank you for this demo, i have one doubt in drawing lines that after finishing all these calculations. researchers are drawing the parallel lines over the bright fringes as well as some people are drawing over the dark portion, which one is correct. My observation from this demo is may be both are equal. could you clarify ? Thanks in Advance.....

Nice explanation Dr. Jayadeep..keep it up..
Thank you for great lecture professor.
I have one question though.

In that case only angle is different and the lattice spacing is same?
or the differed angle means that the changed of (hkl) ?
You are absolutely right! The different angle means a different (hkl).
@ Ah, then, In one crystal we can find different types of lattice spacing by selecting different spots from FFT image?

@@JeyadheepanK Thank you so much sir!!
Thanks for such a nice explanation
..... U explained very well.
You are welcome!
Thank you sir very clear tutorial
amazing, thank you too much for this I was searching for a software to do FFT then inverse FFT and I have found you. So, thank you again.
Glad I could help!
Thanks for this video to measure d-spacing by a free software
Thank you for the explanation.
we dont have to further divide the value into 2 for getting d -spacing ?
is lattice fringe is same to d spacing ?

I have set the scale to nm. For FFT, the scale is nm but for inverse FFT the scale comes in pixel. Why??
Thank you very much sir very useful video. I want to know we got only one d space value. what to do next with this value? For hkl indexing what we can do? i don't have saed pattern.
Good day Sir. In selecting the spots in the FFT with the oval tool. can I select the bright spot in the middle?
Any bright spots....
Thak you sir, very easy technique to find the d-spacing
Thank you, sir, for this useful video...I have a question, for the last part, why is it can be 0.407 nm or 4.07 nm? Thank you.
Sorry... I was wrong ... It's 0.407 nm or 4.07 A°
@@JeyadheepanK what mistake you do here sir
@@kutraleeswaran Didn't understand your comment...
@@JeyadheepanK you said I was wrong.... It's 0.407nm or 4.07A, that's why I'm asking.....
Thank you sir thanks your response
I am not able to get the image after doing inverse FFT. It giving me back the same image. I don't know what I am doing wrong. Please help
It is saying no pixel has been set to 0 (black) or 255 (white) so filtering will not be done. What does that mean?
You might have miseed a step in which you have to select a point in fft image and mask it with a round and white color... Please watch the video again madam.

Why can't I find the draw option after doing the perpendicular line..!!!
Use Cntrl+D or find in "Edit" Menu

Both are correct...
Fringe width and D spacing are same ??.
Yes
