How to calculate FWHM of beam profile
5 views (last 30 days)
I had acquired an image. After that, I plotted a beam profile from that image (as shown in attached picture below). I need to evaluate the FWHM of that beam profile in order to obtain distance between two point at half of maximum value.
The other problem I had faced is the noisy at pixel number 51 - 52.
My idea is to eliminate the noisy pixels and evaluate the FWHM. But, I dont know how to do it since the beam profile was flipped. Anyone know how to do it?
