Abstract:
1. A 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 that includes at least one digital filter, the digital filter including one or more filter kernels, the method comprising: 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; calculating a post-processing performance metric that is a function of the modeled propagation; and jointly designing the optical subsystem and the digital filter based directly on the post-processing performance metric and subject to size and/or footprint constraints on the digital filter, wherein the step of jointly designing the optical subsystem and the digital filter comprises adjusting coefficients of the filter kernels and adjusting footprints of the filter kernels.
