Expected Energy Method for Electro-Optical SNR Calculations.

Abstract

A mathematically robust methods is derived that allows the signal to noise ratio (SNR) of an electro-optical system to be estimated when a point source image falls onto a sensor array of discrete picture elements (pixel). The derivation is based on a geometrical analysis of image and sensor element configuration. This method allows the optimal pixel size to be selected to maximize the expected SNR for any point source image once its diameter is known. In this report the method is used to determine the probability of an image falling into one, two, ..., six pixels as a function of image diameter and pixel size, and the corresponding expected maximum signal. Examples are given using this method to estimate the SNR for an electro-optical system. (Author)
