Physics Based Simulation of Night Vision Goggles

Abstract

Night vision goggles (NVGs) are a head-mounted, head-steered sensor designed to allow an aviator to operate at night with increased operational capability and situation awareness. NVGs greatly enhance an aircrew's ability to conduct night operations and are used extensively in both rotary- and fixed-wing operations. NVGs provide an intensified image of scenes illuminated by ambient energy that exists in the night environment. NVGs (generation III) amplify energy in a certain portion of the electromagnetic spectrum 2,000-7,000 times. They are sensitive in the red and near infrared (approximately 600-900 nanometers). In fact, there is little to no overlap in the ranges of sensitivity of the human eye and NVGs. The resulting imagery has some special characteristics that influence human perception and operational employment that drive a requirement for realistic imagery to support simulation-based training and mission rehearsal.
