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.
