Applicability of a commercial twisted-nematic liquid-crystal display is examined at approximately 400 nm. Different modulation modes predicted by Jones-matrix calculus are experimentally tested. High contrast amplitude modulation with negligible loss, high contrast and low loss hybrid ternary modulation, and 1.5pi continuous phase delay without intensity modulation and with low loss are presented. Simulation results of a 4f holographic system prove the usefulness of the high contrast for amplitude modulation, and the importance of pi phase difference between high transmission white levels in a hybrid ternary modulation.
在约400纳米波长下对一款商用扭曲向列型液晶显示器的适用性进行了研究。通过实验测试了琼斯矩阵算法预测的不同调制模式。展示了具有可忽略损耗的高对比度幅度调制、高对比度和低损耗混合三元调制以及无强度调制且低损耗的1.5π连续相位延迟。一个4f全息系统的模拟结果证明了高对比度对幅度调制的有用性,以及混合三元调制中高透射白色电平之间π相位差的重要性。
