2018年5月28日 · LCoS是Liquid Crystal on Silicon（硅基液晶）的缩写，LCoS空间光调制器是基于LCoS芯片，利用液晶的光电效应对光场进行调制的光学器件。 由于 LCoS 自身不透光的特点，不能作为透射式光调制器使用，但 LCoS 自身反射率很高，能够作为反射镜使用，因此适合做反 …

In this work we propose different types of combination of several diffractive lenses written onto a single programmable liquid crystal display (LCD) in order to increase the depth of focus (DOF) of...

2004年8月15日 · The working models of LCoS (Liquid Crystal on Silicon) were optimized in parameter space by simulation. Two modes were selected, which were suitable for phase modulation. One was the RTN-52° mode, the other was parallel alignment ECB mode. Phase changes were measured when various voltages are applied to LCoS.

2009年9月1日 · Here, we have characterized an Electrically Controlled Birrefrigence (ECB) LCoS display that allows us to manipulate the electrical signal addressed to it. Then, by selecting the appropriate electrical signal we can increase or decrease the fluctuation phenomena.

Liquid crystal (LC)-based active metasurface is one of the most promising approaches due to the well-established LC industry. In this paper, an electrically tunable active metasurface was proposed and experimentally demonstrated using photoaligned nematic LC. The good quality of the LC photoalignment on the metasurface was demonstrated.

Digital addressing of the electrical signal in spatial light modulators, as it is the case in present liquid crystal on silicon (LCoS) displays, may lead to temporal phase fluctuations in the...

In this paper, we will focus on LCOS SLMs with the positive dielectric nematic LC in the anti-parallel aligned ECB mode. The LCOS response time mainly consists of the LC switch-on time ( ) and the LC switch-off time ( ).
