Paper Abstract

One obstacle to optimizing performance of large-scale coded aperture systems operating in the diffractive regime has been the lack of a robust, rapid, and efficient method for generating diffraction patterns that are projected by the system onto the focal plane. We report on the use of the 'Shrekenhamer Transform' for a systematic investigation of various types of coded aperture designs operating in the diffractive mode. Each design is evaluated in terms of its autocorrelation function for potential use in future imaging applications. The motivation of our study is to gain insight into more efficient optimization methods of image reconstruction algorithms.
