Abstract
An imaging system with a diffractive optic captures an interference pattern responsive to light from an imaged scene to represent the scene in a spatial-frequency domain. The sampled frequency-domain image data has properties that are determined by the point-spread function of diffractive optic and characteristics of scene. An integrated processor can modified the sampled frequency-domain image data responsive to such properties before transforming the modified frequently-domain image data into the pixel domain.
