Linear resolution enhancement

This paper describes the tradeoff between resolution and noise that exists in imaging systems that employ computer compensation of the input point spread function. Emphasis is placed upon systems having circularly symmetric blur degradation, particularly the Airy and the Gaussian spots. The paper describes how “optimum” deconvolutional processing arrays can be efficiently computed. Quantitative results are given for Airy and Gaussian spot compensation under a variety of image sampling raster dimensions and patterns.
