Abstract
A new principle of acoustic scanning of an optical image is described. The illumination modulates the storage time constant of a charge grating acoustically stored in a p−n diode matrix. One surface acoustic pulse directly reads out the resulting charge distribution. Owing to integration effects, the device exhibits a very high sensitivity and an electronically variable contrast.Keywords
