Electrooptic Laser Scanner for TV Projection Display.
An experimental laser TV projection system was constructed using electrooptic prisms of ammonium dihydrogen phosphate to furnish high speed horizontal scanning. Horizontal resolution comparable to 300 TV lines was achieved without a bothersome temperature rise in the electrooptic elements. The drive power required for the electrooptic scanner is about 65 W delivered through a transistorized electronic switch.
