STUDY OF IMAGE-EVALUATION TECHNIQUES.

Abstract

Numerical results are given for various diffraction functions for optimum balanced third-order spherical aberration. The sampling theorem is applied to optical diffraction theory. The dangers inherent in optimum balancing techniques are discussed. The total illuminance of an optical system is computed from the design data for rotationally symmetric aberrations. The optical transfer function is determined directly from the edge spread function. A method of calculating the transfer function of an optical system in the presence of off-axis aberrations is introduced.
