Фундаментальные ограничения точности совместных измерений параметров оптических полей

Abstract

The investigation of the fundamental restrictions for the joint measurement limiting error of the optical field parameters based on the semiclassical theory of photoelectric detection and the information theory has been performed. In the frames of 1D 4-parsmetric and 2D 7-parametric Gauss model with the background under the assumption of Poisson count statistics the examination of the absolute and conditional minimal variance matrix boundary has been realized. The numerical investigation of the background and dark current noise effects, the size and position of the measuring region relative to the center of the field is given for light sensitive matrixes with different number of elements.
