HRTEM d-spacing measurement

A short demo on the d-spacing measurement out from an HRTEM image using the tool ImageJ

[@sureshphilip1280]

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 🙏

[@uzmasubhan877]

Thanks for such a nice explanation ..... U explained very well.

[@dr.d.arivukarasan4442]

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 KZbin too...... Congratulations sir....

[@Arahul92]

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.

[@saddamiraqui1686]

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.

[@karthickk2573]

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

[@deepamakhija1346]

Nice explanation Dr. Jayadeep..keep it up..

[@SuezScience]

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.

[@JeyadheepanK]

Glad I could help!

[@abiyyukenichi1250]

Thank you sir very clear tutorial

[@karthisrivi]

Thanks for this video to measure d-spacing by a free software

[@doc.dr.sezaikutuk]

Thank you for the explanation.

[@ajaynimbalkar7389]

Thak you sir, very easy technique to find the d-spacing

[@kalaipriyaaesthetics4042]

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.

[@chautran3379]

Thank you. It really helps.

[@ahmadfadhil5493]

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.

[@JeyadheepanK]

Sorry... I was wrong ... It's 0.407 nm or 4.07 A°

[@kutraleeswaran]

@@JeyadheepanK what mistake you do here sir

[@JeyadheepanK]

@@kutraleeswaran Didn't understand your comment...

[@kutraleeswaran]

@@JeyadheepanK you said I was wrong.... It's 0.407nm or 4.07A, that's why I'm asking.....

[@kutraleeswaran]

Thank you sir thanks your response

[@simrankour572]

I have set the scale to nm. For FFT, the scale is nm but for inverse FFT the scale comes in pixel. Why??

[@96simplegirl]

we dont have to further divide the value into 2 for getting d -spacing ? is lattice fringe is same to d spacing ?

[@prantisutar5363]

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

[@prantisutar5363]

It is saying no pixel has been set to 0 (black) or 255 (white) so filtering will not be done. What does that mean?

[@JeyadheepanK]

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.

[@chautran3379]

@@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.

[@sthitimuduli3490]

Why can't I find the draw option after doing the perpendicular line..!!!

[@JeyadheepanK]

Use Cntrl+D or find in "Edit" Menu

[@venkatesenjayaraman7894]

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.....

[@JeyadheepanK]

Both are correct...

[@uthmanalli2418]

Good day Sir. In selecting the spots in the FFT with the oval tool. can I select the bright spot in the middle?

[@JeyadheepanK]

Any bright spots....

[@gayatreeshinde7905]

Fringe width and D spacing are same ??.

[@JeyadheepanK]

Yes
