Özet
Night vision goggles (NVGs) are head-worn display systems that support visual performance under low-illumination conditions, yet the perceptual effects of phosphor screen type remain incompletely understood. In particular, direct empirical comparisons of white-phosphor (P45) and green-phosphor (P43) NVG displays under degraded visual conditions are still limited. This study evaluated object recognition performance with white- and green-phosphor NVGs in a field-based night experiment involving 40 military helicopter pilots. Participants identified aviation-relevant objects across nine progressively blurred image conditions, and recognition performance was scored on a 0–20 scale. Stratified Cochran–Mantel–Haenszel analysis showed that white-phosphor NVGs were associated with substantially higher recognition odds than green-phosphor NVGs (common OR = 4.12, χ2(1) = 140.11, p < 0.001). Recognition advantages for white phosphor were especially noticeable at intermediate blur levels, where higher recognition scores were observed. Although object-level onset differences were not statistically significant in all comparisons, the overall results indicate that phosphor type may influence visual recognition efficiency under degraded viewing conditions. These findings suggest that white-phosphor NVG displays may offer perceptual advantages for object recognition tasks and may be relevant to the design and evaluation of near-eye display systems for low-light operational environments.
