Liquid crystal on silicon (LCOS) device is a potential candidate for spatial light modulators (SLMs) due to its high resolution and the wide range of tunable phase retardation. Besides the telecom applications, SLM is also very promising for display applications, especially for the augmented reality (AR) displays. In this paper, we will discuss the advantages of analog LCOS SLM compared with the digital one. A 0.6‐in short‐loop sample test result with precise cell gap controlled is discussed. A fast liquid crystal with high birefringence that attains less than 2.5‐ms full‐on–full‐off response time is also introduced. Regarding the computer‐generated hologram (CGH), a new algorithm called multiconstraints angular spectrum algorithm (MASA) is proposed to enhance the image quality of dual‐plane holographic projection.

适用于AR显示应用的模拟LCOS SLM设备

硅基液晶（LCOS）器件具有高分辨率和宽范围的可调相位延迟，因此是空间光调制器（SLM）的潜在候选者。除了电信应用程序之外，SLM在显示应用程序中也非常有前途，特别是对于增强现实（AR）显示器。在本文中，我们将讨论模拟LCOS SLM与数字LCOS SLM相比的优势。讨论了0.6英寸短循环样品测试结果，其中精确控制了细胞间隙。还介绍了一种具有高双折射的快速液晶，该液晶的全开全关响应时间不到2.5毫秒。关于计算机生成的全息图（CGH），提出了一种称为多约束角谱算法（MASA）的新算法，以提高双平面全息投影的图像质量。
