Update on Laser Noise Data Collection and Analysis: Dynamic CSD and PSD Plots |
|
|
| An update on the CSD/PSD code:
The code is now taking a dynamic average of the points, and that has significantly reduced the noise that we were reading and the issues I was having with the lines in the plots. The graph for the CSD is still putting up a fight though, and amassing many lines that do not appear when just scatter plotted. I plan to fix that tomorrow, alongside inserting my own generated signal into the data. I have plotted the coherence alongside these graphs (as shown in the first screen recording and in one of the images), and it is significantly less than 1-- starting at or below 10^(-1).
As a note, I am unsure of why the raw data looks like this-- the laser goes through periods of extreme noise and I think this data was taken during one of them. |
