Computer-aided design of diffractive optical elements

A number of iterative algorithms for calculating kinoforms are discussed: a multiplicative adaptive algorithm allowing the rate of iterative process to be increased, fast algorithms for interpolating and extrapolating the kinoform phase pixels, an algorithm for calculating kinoforms forming radially symmetrical images and axial light segments, an algorithm for calculating formators of Gauss-Hermite modes in required diffraction orders, and an algorithm for calculating formators of reference wavefronts. The results of computer simulation are given.
