Abstract:
With the growth of efficiency of computational tools, iterative design of diffractive optical elements (DOE) has become widespread. The well-known search procedures (Fienup’s procedures and gradient procedures) essentially do not converge to a global extremum. If the solution of the direct problem does not require high computational costs (for example, in the case of a radially symmetric DOE), it is advisable to use stochastic algorithms for global optimization of a DOE phase. This paper discusses the application of the well-known genetic procedure for finding the extremum of a multivariable function to the design of binary radially symmetric DOEs. The radially symmetric nature of the DOE phase allows to perform efficient calculations on an ordinary personal computer. The results of numerical and natural experiments are presented.
