Imaging system with variable opto-mechanical system, aberrated optics and compensating filter bank

摘要

A weighted sum of a set of component filters is used to effectively apply different composite FIR filters to compensate for aberrations resulting from different opto-mechanical settings. The FIR filters are composite in the sense that they are a weighted sum of the set of component filters. In one approach, the aberrations vary as a function of the opto-mechanical setting, and the opto-mechanical setting is used to determine the weights of the different component filters.
