摘要：
A display system wherein a laser light source (10) is pulsed to deliver a sequence of light pulses to an acousto-optic cell activated via a piezo-electric transducer (13) with an information bearing input signal which propagates the information across the cell in the form of sound waves. The laser is pulsed in synchronism with the carrier frequency of the input signal so that the light pulses are modulated in accordance with the information, and the modulated light pulses are projected via an optical scanning system (15, 16, 18).
