Abstract
The spatial light modulator based on total internal reflection at the ferroelectric liquid-crystal-glass interface has a 10(7):1 contrast ratio, a 250-micros response time, and a lambda/8 transmitted wave-front uniformity. These properties make the spatial light modulator well suited to provide frequency-band excision in acousto-optic spectrum analyzers.Keywords
