Abstract

Fisher-information-based optimization of a conventional phase diversity speckle imaging system is presented. I demonstrate how Fisher information can be used to determine the optimum value of defocus in the diversity channel for estimating the mid-frequency integrated object power spectrum. This approach is likely to be useful in optimizing the design and performance of a general imaging system.
