Paper Abstract

The U.S Army Night Vision and Electronic Sensors Directorate (NVESD) evaluated a wide field of view HMD technology demonstrator developed by Kaiser Electronics. Primary performance and design characteristics addressed are total field of view, system contrast transfer function, eye box parameters, binocular alignment/stability, residual distortion and head borne mass. The HMD technology demonstrator was designed and built within one year between 1999 to 2000 and was developed to prove novel design and fabrication concepts in the visor, relay optics, optical interfaces, and optical platform structure. The HMD technology demonstrator system is based on a modified HGU-55 helmet and utilizes a bifurcated visor design resulting in a total head borne weight of 4.11 lbs (including MBU-20P Oxygen mask). The system provides a maximum binocular field of view of 52.7° X 29.6°and binocular overlap of 29.5° with an on-axis limiting resolution of 0.76 cy/mr. The uncompensated binocular misalignment was less than 0.29 mr RMS horizontal and 0.24 mr RMS vertical. Other useful system characteristics include right/left independently adjustable IPD mechanisms and a visor/display retraction and removal mechanism operable with a single gloved hand.
