CORRECTION OF FOCUSER PHASE FUNCTION BY COMPUTER-EXPERIMENTAL METHODS

N. L. Kazanskii

Abstract:
Within the Fresnel-Kirchhoff approximation, consideration is given to the distribution of light in the focuser's focal plane into a narrow longitudinal interval along the optical axis. To improve the uniformity of intensity distribution along the focusing interval an iteration procedure is suggested for the correction of the focuser phase function. The results of a computer experiment with the original and the corrected optical elements are presented.
