The spatial light modulator based on total internal reflection at the ferroelectric liquid-crystal–glass interface has a 107:1 contrast ratio, a 250-µs response time, and a λ/8 transmitted wave-front uniformity. These properties make the spatial light modulator well suited to provide frequency-band excision in acousto-optic spectrum analyzers.
