Abstract
A multi-spot light modulator using a laser diode is disclosed in which a single light pulse from the laser diode generates a multi-spot image of a data pattern, each spot corresponding to an active bit of the data pattern. The ability of a pulsed laser diode to generate a narrow light pulse is used to image an acoustic wave corresponding to the data pattern without the normal degradation in resolution caused by the motion of the acoustic wave.
