Abstract:

Experimental testing of 10 subjects wearing the ANPVS-5A II GEN night vision goggles NVG and ANVIS III GEN NVG was conducted under field conditions of ambient starlight illumination approx. 10-5 mL. The parameters measured were 1 binocular visual acuity BVA, 2 stereopsis depth perception, and 3 a subjective forced choice test. Results showed that BVA was 20124 and 2086 for the II and III GEN NVG, respectively. This difference was statistically as well as clinically significant. The stereopsis test results were inconclusive and variable because of the limited sample size and relative inexperience of the subjects in using NVG. Neither BVA nor stereopsis with the NVG was found to be related to standard baseline measures of these parameters in the clinic. Even though the ANVIS has better gain, resolution and sensitivity, 6 out of 10 subjects preferred the ANPVS-5A for viewing the subjective test. This seemingly paradoxical finding was surmised to be a result of the presence or lack of scene contrast due to the differential sensitivities in the II and III GEN photocathode tubes.
