Description
Summary:Laboratory measures of stereopsis and field measures of relative depth discrimination while using the AN/PVS-5 Night Vision Goggle were determined and compared with data of unaided eye performance. Using a modified Howard-Dolman apparatus, the stereoscopic threshold was found to be considerably degraded with the man-goggle system when compared to photopic unaided eye performance. Field measurements of relative depth discrimination using all available visual cues showed that performance of the man-goggle system was statistically equivalent only at intermediate distances of 500 feet or less.
