摘    要:提出了利用记忆型模拟回火退火算法来进行基于晶体双折射的光学有限脉冲响应滤波器设计的新方法,用以实现任意光谱响应双通道输出。模拟退火算法模拟了固体缓慢退火从而获得最低内能的物理过程,是一种简单而有效的随机性全局优化算法。应用具有记忆功能的回火退火算法,在较少的晶体延迟片数目下,实现了较优的设计。为证明该设计方法的可行性和有效性,给出了宽波带绿色/品红(Green/Magenta,G/M)滤波器的设计实例以及实验结果。初步研究表明,所设计结果完成满足LCOS投影分合色的要求。

关 键 词:模拟退火算法  光学有限脉冲响应滤波器  设计方法  晶体双折射  任意光谱输出

Abstract:The memory simulated annealing approach is presented for designing an optical FIR filter based on crystal birefringence, which is able to provide arbitrary spectrum output with double channels. As an effective way to make global optimization through random search, simulated annealing algorithm simulates the slowly physical process of solid annealing to get lowest inner energy. The procedure of employing the algorithm to get satisfied results in relatively fewer crystal slices is described, and an example of broadband G/M filter, including the experimental results is given to demonstrate its feasibility and effectiveness.
Keywords:optical filter  finite impulse response (FIR) filter  simulated annealing algorithm  arbitrary spectrum output  crystal birefringenc
