DESIGN OF AN AIRBORNE HELMET MOUNTED DISPLAY.
Abstract
The report describes the laboratory tests and design studies accomplished for the preliminary design of an airborne Helmet Mounted Display (HMD). The HMD design allows the airborne simulation of several sizes of TV displays. By changing the optics used in the HMD, apparent display sizes from 6 inches to 22 inches can be provided at an apparent viewing distance of 18 inches. Five sets of interchangeable optics can be changed inflight to provide the various display sizes. A high resolution CRT provides a high quality TV picture under all magnification conditions. The headset is designed to be easily installed, adjusted and removed in-flight from either the Navy or Air Force standard helmet. An electronics unit with operator controls drives the headset. The HMD is designed to operate with either 575 or 875 line TV input, 30 Hz frame rate and 2:1 interlace. (Author)
