Abstract

Direct search with random trajectory (DSRT) method applied to the task of minimization of kinoform synthesis error is similar to direct binary search method for binary holograms synthesis. Main difference is that used method is designed to process arrays with multiple phase levels. First, kinoform is generated with conventional method such as Gerchberg-Saxton. Then, elements of kinoform are sequentially switched to obtain lower synthesis error value. This process goes on until minimum error value is reached. Analysis of performance of the DSRT method depending on kinoform size and number of phase levels is conducted. Results of numerical experiments are presented.
