%X In order to reduce the calculation amount and improve the design precision of binary optical elements,a two-step simulated annealing algorithm is introduced based on the analysis of the present algorithms.The quantized phase data is used in this algorithm and the whole annealing procedure is divided into two steps.Step 1 search and lock the best solution area.Step 2 approach the desired phase data fleetly.Compared with traditional method,simulated test result demonstrates that the algorithm maintains the strongpoint of global optimization,and has better steadiness and greater efficiency.The algorithm also eliminates quantization error and design result is improved.A single-focal plane focusator is designed by using the algorithm and a preferable experimental result is achieved.
