Magneto-optic display
First Claim
1. A binocular magneto-optic display comprising:
- (a) a source producing a first beam of light;
(b) first polarizer means disposed in said first beam for polarizing the light of said first beam;
(c) first magneto-optic chip means disposed in said first beam after said first polarizer means for selectively altering the axis of polarization of said first beam passing through addressible areas of said first chip, said first chip including means adapted to be operably connected to a first display driver for addressing said addressible areas whereby said first chip can be driven to alter the axes of polarization of said areas as a function of a desired first display;
(d) first polarization analyzer means disposed in said first beam after said first chip means for blocking or passing portions of said first beam corresponding to respective ones of said areas through which they have passed as a function of said altering of the axes of polarization performed by said respective ones of said areas whereby said desired first display is imparted into first light beam;
(e) first beam splitter means disposed in said first beam for splitting said beam into first and second partial-intensity beams;
(f) focusing means disposed in said first and second partial-intensity beams for viewing said first display contained within said first and second partial-intensity beams; and
,(g) second beam splitter means disposed in said first and second partial-intensity beams after said focusing means whereby a viewer can look through said second beam splitter means and see said display superimposed on a normal field of vision.

Abstract
A display adapted to be helmet-mounted or used for projecting and having the multi-mode capability of full three-primary color displays; gray scale or halftones; stereo imagining; image processing; split-screen operation; blink comparator; see-through, heads-up viewing; and night-vision intensification combined with alpha-numerics. A bulb in a reflective housing illuminates a plastic diffusion screen to create a light beam. An electronic alterable, random-access storage display chip is placed in line with the emerging beam. The display chip comprises a film sandwich configuration consisting of a sheet polarizer, a magneto-optic chip with addressible alterable areas, and a sheet polarization analyzer. Signals received from a radio link are applied through a cable and connectors to the chip. By driving the chip as a function of the desired display, the display is impressed on the beam of light which may then be split and passed through appropriate focusing lenses for viewing or projected. Multiple beams, multiple display chips, and multiple layered chips with filtering are employed to create various operating modes.
