Abstract
AN IN LINE HELMET OR HEADSET MOUNTED AUDIO-VIDEO INTERACTIVE DISPLAY DESIGN IS PRESENTED THAT HAS ALL OF THE IMAGING AND PROJETION DEVICES ON OR NEAR A FLIP UP FACEPLATE OR VISOR. NO SIDE OR TOP MOUNTED CRT AND PROJECTION LENS IS USED AND AMBIENT LIGHTING IS A REALISTIC POSSIBLE OPTION FOR DISPLAY ILLUMINATION. THE SEE THROUGH QUALITY OF THE DEVICE DEPENDS ON THE POLARIZATION SELECTION PROPERTY OF A CASCADED SANDWICH OF TWO HOLOGRAPHICALLY PRODUCED OFF AXIS ZONE PLATES. THE SANDWICH IMAGES A SMALL LCTV AT NEAR INFINITY AND SIMULTANEOUSLY ACTS AS AN ANALYZER TO VIEW THE ROTATED COMPONENTS OF LIGHT EXISTING FROM THE LCTV. UNDIFFRACTED LIGHT PASSES STRAIGHT THROUGH THE HOE WITH NO IMAGE CONTENT AND CONTAINS THE REAL WORLD VIEW. ILLUMINATION MAY BE AMBIENT AND GRATING DIRECTED OR FROM VARIOUS INTERNAL SOURCES SUCH AS LEDS, LAMPS, GAS DISCHARGES AND DIODE LASERS. COLOR AND STEREO DISPLAYS ARE POSSIBLE ALONG WITH DUPLEX AUDIO COMMUNICATION AND KEYBOARD COMPUTER INTERFACE.
