Polarization Encoding for Multi-channel Optical Encryption using Twisted Nematic Liquid Crystal Displays
Chau-Jern Cheng, M. S. Chen, Han-Yen Tu · 2006
This study proposes and demonstrates the multiple polarization-encoding scheme with the cascaded twisted nematic liquid crystal spatial light modulators for multi-channel exclusive OR logic optical encryption. Both analytical and experimental results are presented and discussed.
