As I already searched, in OpticStudio has at least 3 ways to express the phase, 1st is shown in the type of Huygens PSF, 2nd is shown in the type of FFT PSF, 3rd is shown in Beam File Viewer. But I am not clear what are the differences among them. I also compare the figures among them, they looks different. So I ask the question here, maybe someone can answer me. Thanks in advance!
