Abstract

The human visual perception performance results of a dual band near (intensified) and long wave (thermal imager) sniper scope are modeled. This system combines an uncooled focal plane array based thermal imager with an intensifier tube to provide a dual band image. The resulting fused image can obtain any percentage combination of thermal or intensified imagery. A multi-spectral common aperture is utilized to provide parallax free registered images in each spectrum necessary for the sniper scope application. A custom designed eyepiece with a micro display overlays the thermal channel image onto the intensified image. The intensified image is viewed directly on the fiber optic output of the intensifier allowing up to 64lp/mm intensified resolution, equivalent to 2300 resolvable lines maintained in the intensified channel when moonlight is available. A system of this type combines the very high line resolution available from intensifiers with very high spot detection for targets of military interest. The results of an analysis of human visual performance using NVThermIP and IINVD are presented for this dual band common aperture sniper scope.
