Optical system with segmented pupil function

摘要

A method for designing a pupil function for use in an imaging system, comprising:
selecting a pupil function;
calculating a sampled PSF, taking into account characteristics of the imaging system and the pupil function;
evaluating the sampled PSF in accordance with a selected metric; and
if the sampled PSF does not conform within the selected metric, then
modifying the pupil function, using a set of parameter modifications, and
repeating the evaluating and modifying of the pupil function until the sampled PSF conforms within the selected metric.
