摘要：

High speed scanning/deflection of monochromatic laser beams is essential to advanced optical systems and require random and or sequential scanning of laser spot over an image plane. We have developed a beam steering device (BSD) based on a polarization sensitive BSD element which either transmits or reflects a beam of light. This device exploits optical properties of cross linkable cholesteric liquid crystal (CLC) silicones. The CLC, with a halfwave retarder, can be used to make a basic building block of a scanner/electro-optical crossbar switch. This device is compact, operates in microsecond second range at similar to 30 Volts (possibly less).
