Impact of Visor Transmissivity and Reflectivity on Pilot Visual Acuity and Target Acquisition Range.

摘要

The purpose of this study was to experimentally determine the impact of varying degrees of visor transmissivity and reflectivity on visual acuity. This study measured pilot's target detection range when wearing six different visor configurations: (a) no visor, (b) USAF tinted visor, (c) the Visually Coupled Acquisition and Targeting System (VCATS) 25% transmissive visor with a 9% reflective coating, (d) the VCATS 25% transmissive uncoated visor, (e) the VCATS 35% transmissive uncoated visor with a 13% reflective coating. The results of this study showed that detection range decreased as transmissivity was decreased while detection range remained unchanged as reflectivity was increased.
