Abstract:
An aperture mask for image plane exit pupil characterization of an imaging system is disclosed. The aperture mask includes a substantially opaque sheet configured to block portions of a wavefront travelling through an optical path of the imaging system, the sheet includes a plurality of holes, wherein the holes are positioned relative to each other such that a hole-to-hole distance generates a unique spatial frequency signature in the imaging system's point spread function.
