Paper Abstract

Methods of determination of coordinates of the center of a narrow radiation beam by means of the CCD array are considered. For the continuous representation of images and noises the analytical expressions describing signal and noise functions at the output of optimal spatial filter are obtained, as well as the dispersion of optimal estimation of a position of Gaussian radiation beam. It is shown that using the CCD array the minimum error of estimation of the Gaussian beam position is observed when the beam effective diameter is approximately equal to 0.8 of lateral length of a light-sensitive cell of the array.
