COMPUTER-AIDED-DESIGN OF DIFFRACTIVE OPTICAL-ELEMENTS

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