An Assessment of a Proposed Method for Adjusting and Focusing Anvis Night Vision Goggles

An assessment of a proposed method for adjusting and focusing ANVIS night vision goggles.

Night vision goggles are becoming an increasingly important tool in military aviation. They provide superior visual capability over unaided night vision, but any reduction in goggle performance can have a serious effect on flight safety and operational effectiveness. This study shows that the use of a standard adjustment procedure in a night vision goggle (NVG) test lane, with a resolution char...

Civilian use of night vision goggles.

Civil aviation operators have expressed an increased interest in conducting night operations with night vision imaging systems. The development of special operational concepts, hardware requirements, training requirements, and regulatory change and oversight is necessary to control for the known performance constraints associated with these devices. In 2001, the Aerospace Medical Association in...

Visual Acuity and Stereopsis with Night Vision Goggles

Image Contrast and Visual Acuity Through Night Vision Goggles

Night vision goggles (NVGs) intensify ambient illumination making it possible to see in the dark despite insufficient light for normal vision. NVGs are used for military and civilian operations, and as visual aids for night blindness. The quality and quantity of vision achieved through NVGs depends on several factors including the intensity of ambient radiation, the integrity of NVG electro-opt...

Detection of Motion-defined form using Night Vision Goggles

Perception of motion-defined form is important in operational tasks such as search and rescue and camouflage breaking. Previously, we used synthetic Aviator Night Vision Imaging System (ANVIS-9) imagery to demonstrate that the capacity to detect motion-defined form was degraded at low levels of illumination (see Macuda et al., 2004; Thomas et al., 2004). To validate our simulated NVG results, t...
