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