Vibratory scan optical display
First Claim
1. A raster-type personal display system for providing an image of displayed information in the field of view of an observer, comprising:
- means for mounting a mirror in the field of view of an observer,a plurality of light sources,an array of fiber optic filaments mounted in a cantilever arrangement and each having one end in a fixed position to receive light from said sources and a second end positioned to be visible to an observer by the mirror and free to translate within fixed display limits,means for imparting a vibrating motion to the second end of said fiber optic filaments within the fixed display limits to produce a two dimensional display reflected from the mirror to the observer, andmeans responsive to drive signals to energize said plurality of light sources in a pattern to display desired information at the vibrating second end of said fiber optic filaments.

Abstract
A raster-type personal display is provided by vibrating an array of fiber optic filaments (32) between display limit (52, 54) by means of an electromechanical exciter (36). One end of the fiber optic filaments (32) is cantilever mounted to an array of light emitting diodes (34), with the second end of the filaments free to be vibrated by the exciter (36). Drive signals for energizing the light emitting diodes (34) are generated by a symbol generator (38) that receives synchronization pulses from a position detector consisting of a light source (58), a shutter (56) and a light responsive pickup (60).

8. A raster-type personal display system for displaying information to an observer by means of a mirror mounted in the field of view of the observer, comprising:
-
a plurality of light sources, drive means responsive to input signals to energize said light sources in a pattern to convey the desired information, an array of flexible fiber optic filaments each having one end fixedly mounted in a position to receive light from said sources and a second end free to translate within fixed display limits from an equilibrium position, means for imparting a vibrating motion to the second end of said fiber optic filaments within the fixed display limits to provide a two dimensional image reflected from the mirror to the observer, and means for detecting the position of the second end of said fiber optic filaments to generate a synchronization signal to said drive means and said means for imparting a vibratory motion. - View Dependent Claims (9, 10, 11, 12)

13. A raster-type personal display system for providing an image of displayed information in the field of view of an observer, comprising:
-
binocular vision means to be worn by an observer and including lenses through which objects are observed in a conventional manner, a mirror mounted in one of said lenses in the field of view of an observer, a plurality of light sources, an array of fiber optic filaments having one end mounted to said binocular vision means, each filament positioned to receive light from said light sources and a second end positioned to be viewed by an observer through said mirror, and means for imparting a vibrating motion to the second end of said fiber optic filaments to produce a two-dimensional display reflected from the mirror to the observer. - View Dependent Claims (14, 15, 16, 17)
