Abstract:
1. A computer-implemented method for designing an electro-optic imaging system for imaging a source, the electro-optic imaging system including an optical subsystem, a detector subsystem and a digital image processing subsystem, the method comprising executing instructions to cause a processor to effect the steps of: modeling propagation of the source through the optical subsystem, the detector subsystem and the digital image processing subsystem based on a spatial model of the source, wherein the spatial model of the source includes a statistical model of the source, and wherein propagation through the optical subsystem and detector subsystem is modeled by y=Hs+n, where y is an image of the source after propagation through the optical subsystem and the detector subsystem, s is an ideal sampled image of the source, H is a sampled point spread function accounting for both the optical subsystem and the detector subsystem, and n is noise; and jointly designing the optical subsystem and the digital image processing subsystem based directly on a post-processing performance metric that is a function of a mean square error between an ideal image of the source and an image predicted by the modeled propagation of the source through the optical subsystem, the detector subsystem and the digital image processing subsystem.
