论述了平行排列液晶的位相调制理论,进行了理论结果的计算模拟.研制出平行取向TFT型液晶空间光调制器并分析了其位相调制特性.结果表明,此平行取向的液晶空间光调制器可用于位相调制,其调整量优于0.7μm,最小调整步长是0.052μm.在ZYGO干涉仪上进行的位相控制实验,得到了很好的实验结果.
The phase modulation theory of parallel alignment liquid crystal is discussed and the theoretical results are calculated and simulated.The parallel-oriented TFT liquid crystal spatial light modulator is developed and its phase modulation characteristics are analyzed.The results show that the parallel-oriented liquid crystal spatial light modulator can be used In the phase modulation, the adjustment is better than 0.7μm and the minimum adjustment step is 0.052μm. The phase control experiments on the ZYGO interferometer show good experimental results.
