ABSTRACT:
Apparatus for recording a serial line of electrical data as a spatial array of optical data. The apparatus employs an acousto-optic device through which the electrical signal to be recorded is passed as a continuous acoustic wave. The device is illuminated by a laser and imaged onto a recording medium to form an image of the acoustic wave passing through the device. By pulsing the laser just as the acoustic wave fills the device, a line of optical data can be recorded which will correspond to the acoustic wave in the device. By indexing the recording medium and reimaging every time a new acoustic wave just fills the device, an entire raster may be recorded.
