Abstract

An iterative algorithm is described for the computer generation of complementary pupil functions to be used in hybrid incoherent optical systems for bipolar spatial filtering. Through repeated transformations between the Fourier and spatial domains, and the application of constraints in both, the pupil functions are constructed subject to the ultimate constraint that the difference of the associated PSFs result in a desired bipolar spatial impulse response. Minimization of component PSF bias is a major concern. The case of bandpass spatial filtering will be discussed in detail and preliminary results presented.
