| Abstract: | In this paper, the conventional formula, used to design diffractive optical element (DOE) for beam smoothing, is modified. By using the hybrid algorithm merging hill-climbing with simulated annealing, the precise design of the DOE for beam smoothing is completed. Besides the used sampling points in the optimization, the intensity distribution of any uncontrolled points and with any sampling interval on the focal plane is consistent with the demand for beam smoothing. |
