Abstract: A high-speed printer includes a prerecorded multicharacter font stored in holographic form. Selection of a stored character for projection onto a recording medium is accomplished by means of a conventional X-Y acousto-optic deflection system. To achieve justified lines and attractively composed words, the printer must have a variable character- and word-spacing capability. This capability is realized by combining an electro-optic light deflector with the acousto-optic system in such a way as to controllably vary the angle at which an incident light beam interrogates a selected holographic character. For each different interrogation angle, the selected character is projected to a slightly different location along a row of the recording medium. In this way there is provided a vernier adjustment of the positions of characters to be printed.

Abstract: A single color display is produced by projection using a scanning laser beam operating in the visible or ultraviolet and a photoluminescent screen which emits in the visible. Combinations of phosphors may be employed to simulate white or desired colors.

Abstract: A projection visual display system utilizes at least one laser output line in the blue portion of the spectrum together with a phosphor coating which emits at least one additional color. Means for selectively reflecting laser light on the one hand and absorbing it within the phosphor so as to produce phosphor emission on the other hand are described.
