We have developed an algorithm aimed at extrapolating and interpolating phase samplings of optical elements, and able to form the required intensity distribution with high efficiency and accuracy. When applied to the tasks of calculating kinoform-typ

Using numerical and analytical approaches, we have computed the optical elements (focusators) required for focusing laser light into a narrow ring, a wide ring and a set of rings. A numerical comparison of the various computational techniques is repo

We propose an iterative algorithm for the coherent light field phase retrieval from the modulus of its Hilbert image. It has been shown that the given algorithm is an order of magnitude more insensitive to the data noises than that which retrieves th

A new modernization of the Gerchberg-Saxton (GS) iterative algorithm has been suggested with reference to the task of focusing a coherent monochromatic beam into a preset frequency-plane domain with a given intensity distribution. The modernization p

Three iterative algorithms for calculating kinoforms are discussed: 1) an algorithm for calculating kinoforms with quantized phase forming radially symmetric images, 2) an algorithm for calculating formers of Gauss-Hermite's and Gauss-Leguerre’s mo
