摘要：
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-52degrees mode, the other was parallel alignment ECB mode. Phase changes were measured when various voltages are applied to LCoS. In addition, we showed some results when the LCoS was used as a Fresnel lens. (C) 2004 Elsevier B.V. All rights reserved.
