Abstract
The error of second-order quantization was analyzed, and an optimization algorithm was proposed based on simulated annealing algorithm to optimize the second-order quantized phase data, which could improve the output light field and reduce the error caused by second-order quantization. The simulation results show that the non-uniformity and error function of the DOE output optical field after optimization are reduced from 35.61% to 19.72% and from 27.55% to 16.17%, respectively, showing that the proposed algorithm has certain application value in reducing the error of DOE second-order quantization.
