After extracting the PSF with the Huygens tecnuìique, hoe can one extract its radius and the standard deviation of a gaussian fit superimposed to it?
What I would like to do is take the PSF of my imaging system (which includes a black box lens) and evaluate the radius of the PSF as a function of defocus.
Also I would like to simulate the PSF generated by a homogeneously illuminated pinhole. How would one do that?
The radius can be obtained using the encircled energy plot and operands. If the PSF is Gaussian, you can of course just read the 1/e^2 point directly. If you need to fit the PSF to a Gaussian, you'd need to do that in your own code in say MatLab or Python via ZOS-API.
