Abstract

Helmet-mounted displays (HMDs) provide essential pilotage and fire control imagery information for pilots. However, image quality testers for HMD validation do not currently exist in the field. This research employed techniques from imaging analysis and interpretation, and computer-aided design/computer-aided manufacturing (CAD/CAM) to demonstrate that a portable image quality tester can be developed for HMD validation in the field. For this study, a charge coupled device camera and lens were selected. Hardware characteristics such as viewing angles in horizontal and vertical positions, dynamic working range at day and night, pixel resolution, focal length, and aperture ratio were evaluated with respect to HMD functionality.
