Hi everyone,
Is there a standard way to generate the longitudinal PSF (ie. intensity cross section in the y-z plane) of a focusing lens? I’ve done this two ways, which have similar, but somewhat different results, and want to make sure to use the best method going forward.
- Recording the Huygens Cross Sectional PSF in the image x-y plane when in focus and combining the result with the PSF plots as the image plane is defocused.
- Adding a co-ordinate break just prior to the image plane and rotating the coordinate system by 90 degrees around the y-axis prior to calculating the Huygens Cross Section PSF.
Thanks,
