Switchable Total Internal Reflection Light Deflector

A new digital light deflector, capable of being switched in less than 35 µsec with less than 300 V, uses the principle of switchable total internal reflection. The deflector produces high-quality, high-contrast images and its low cost and high light transmittance make it potentially well suited for use in optical-beam-addressable memory systems as well as for other applications in which random deflection is desirable.
