Abstract

The authors describe an optical system that allows for the bit reversed decimation of an image scene. The optical system consists of a successive sequence of lens arrays. The output of one lens array feeds into the input of the next array. The function of each lens array is to divide the input into its four quadrants. The output of each array is the image formed by summing together the four quadrant images. The goal of this work is to design an optical front end for an imaging system that allows for the simultaneous imaging of both a wide angle field of view and a zoomed telephoto field of view. In addition optimized image acquisition is required for target tracking
