Abstract
A magneto-optic display generator for disposition in a light beam to provide a projectible, directly viewable, or sensible display image. Two separately driven magneto-optic display chips are positioned between a polarizer and an adjustable polarization analyzer. By adjusting the angular relationship between the polarization axes of the polarizer and polarization analyzer, as well as by the use of chips having different Faraday rotations, various visual effects can be created. Such effects as depth of field and the elimination of areas which can be common or not common to both displays can be accomplished.
