Simulated annealing algorithm simulates the slow annealing of solids to obtain the lowest internal energy of the physical process is a simple and effective random global optimization algorithm. By using the tempering annealing algorithm with memory function, the optimal design is achieved with fewer number of crystal retarders. In order to prove the feasibility and effectiveness of this design method, a design example of a wideband green / magenta (G / M) filter and experimental results are given. Preliminary studies show that the designed results meet the LCOS projection sub-color requirements.
