Abstract : An output electrode which is angularly oriented with respect to the reading and scanning electrode is used with associated circuitry to provide a two dimensional image scan for an acousto-optical cell. The output electrode is an interdigitally shaped echelon and intercepts the output signal at a position which is determined by the transit time to a selected step of the echelon. (Author)
