Paper Abstract

The research was designed to determine if night vision goggles (NVGs) with white phosphor displays would enable better object recognition and contrast sensitivity than with green phosphor displays. Thirty-six Maryland National Guard members served in the research. Each performed an object recognition task and a contrast sensitivity task using two binocular NVGs (AN/AVS-9, Model F4949G) that were matched in all respects except that one was fitted with white phosphor displays (P- 45W), while the other had the yellowish green phosphor displays (P-43). Results indicated an overall advantage for the white phosphor for object recognition, but no difference between the phosphors for contrast sensitivity. Questionnaire data indicated a strong preference for the white phosphor NVG.
