Here we present a new developed phase-only LCOS (Liquid Crystal on Silicon) spatial light modulator (SLM) based on an electrically controlled birefringence (ECB) liquid crystal mode for wave front control as well as for dynamic diffractive optics applications, optical tweezing, digital holography ...

在相控 LCOS SLM 调制器中,不会发生由偏振器或其他吸光组件引起的光吸收,因此可以预期获得最大的光效率。 目前,大多数传统的 LC 设备都无法有效地调制入射波前的相位。例如,使用薄膜晶体管的 LC 设备结构不适合相位调制,因为它没有使用适当的电光效应(请参阅“扭曲向列 (TN) 配置”和“VAN 配置”部分)。

In a phase-only LCOS SLM modulator, no light absorption by polarizers or other light-absorbing components will occur, such that the maximum light efficiency can be expected. Figure 1 Structure of phase-only LCOS devices, consisting of transparent top substrate with transparent ITO electrodes, ...

First, the original image is phase encoded and encrypted by a phase key loaded on a liquid crystal spatial light modulator (SLM). Subsequently, the modulated reference light will be overlapped with the object wave to form interference pattern. Finally, the encrypted image hiding can be ...
for every 2-by-2 pixels, we keep the top right and bottom left pixels at 0 as a reference and increase the top left and bottom right pixels jointly from 0 to 255. Without modifying the display layout, we set the camera focus on the SLM and capture the intensity change for the entire...

So it is not straightforward to fully control the light beam by a single phase-only SLM in general. However, full field (i.e. amplitude and phase) control is always highly desirable in order to generate different types of light beams with special properties. In this scenario, a laudable ...
