Large Area High Resolution Eye Piece Display

A miniature wearable head-up display, called a Micro-HM, that permits the wearer to see information superimposed on his field of view wherever he looks, is disclosed in an article entitled "Eye Glass Heads Up Display" published in the Society for Information Display, International Symposium Dist of Technical Papers XII, 48-49 (1981).

This article proposes an elaboration of the system described in the reference and consists of an additional vertical scanning mirror operating at right angles to the existing horizontal scanning optical fiber motion and at a sub-multiple frequency of the horizontal scanning frequency. The purpose of this vertical scanning mirror is to provide additional scanned area in the vertical direction, thus increasing significantly the area to be viewed. By proper design of the system including the microprocessor program, fiber-optics signal generator, and vertical scanning reflecting mirror, it should be possible to provide a virtual image covering the entire field of view of the user.

Optimum image quality should be achievable by proper synchronization of vertical and horizontal scanning motions and LED (light emitting diode) flashing, overlap of successive scans, and adjustment of angle between horizontal and vertical scans.
