Local Optical Limiting Devices Based on Photoaddressed Spatial Light Modulators, Using Ferroelectric Liquid-Crystals
The devices for local light discrimination in the field of view of eye or light-sensitive devices (videocamera, etc.) are discussed, using optically addressed spatial light modulators. The deformed helical ferroelectric (DHF) effect in FLC’s is considered. Different optical schemes of local optical limiting devices with corresponding driving conditions are discussed and the transmission of devices in dependence on FLC parameters (molecular tilt angle) is estimated. The operation of device prototype for local protection of video camera using OASLM and FLC shutter is shown.
