The design of a solid-state laser beam deflector is described for applications requiring line scanning of several thousand resolvable elements. Key features of the system include an optical technique for converting a two dimensional array of pixels to a one dimensional array and a special signal format for activating the pair of acousto-optic deflectors which produce the two dimensional array.
