Abstract
Diffractive optical element (DOE) can be used to realize beam smoothing. In order to realize true beam smoothing, a new design method with a more restrict way in the optimization has been proposed. In this paper, based on this new design method, polarization design is adopted to improve the performance of the DOE for true beam smoothing. The top non-uniformity can be held to be less than 2.7%, no matter which group of sampling points on the focal plane is chosen to be calculated.
