40 PLZT偏光カメラ PLZT偏光カメラを開発した人はまだいない Marom(1997)という人がFLC(ferroelectric liquid crystal強誘電体)型の液晶を使って光ネットワークを構築したが、今後、FLCの代わりにPLZTを使う予定らしい。D. M. Marom, P. Shames, F. Xu, R. R. Rao, and Y. Fainman. Compact free-space multistage interconnection network demonstration. In Optics in Computing, volume 8 of OSA Technical Digest Series, pages , Washington, DC, March 1997.The polarization rotation is done by a FLC array from DisplayTech. The reconfiguration of the network is currently limited by the speed of the FLC device. However, we are developing a PLZT based polarization rotator array which has much faster response times .
