An image quality analysis of ANVIS-6 night vision goggles
… was undertaken in an effort to relate ANVIS-6 Night Vision Goggle image quality to user performance. The purpose was to determine which of five image quality metrics best related to performance tasks. The image quality metrics examined Modulation Transfer Function Area (MTFA), Integrated …

A Nonlinear Finite Element Model of the Human Eye to Investigate Ocular Injuries From Night Vision Goggles
… for ocular injuries to helicopter pilots wearing night vision goggles when the airbag is deployed. A nonlinear finite element model of the human eye was constructed. Ocular structures never before included in finite element models of the eye, such as the fatty tissue, extraocular muscles, and bony …

An investigation of stereopsis with AN/AVS-6 night vision goggles at varying levels of illuminance and contrast
The increased reliance on night operations by the military over the last few decades has led to the development of various night imaging devices. Night vision goggles (NVGs) are one device which have gained widespread use in nighttime helicopter operations. However, rotorcraft accident data have …

Effects of target size, luminance contrast, and illumination on visual target detection and recognition with AN/AVS-6 goggles
… in the development of low light level and night imaging technologies to gain tactical advantages on the battlefield. Moreover, certain military activities such as night aviation maneuvers demand the most sophisticated night imaging devices. Unfortunately, as the frequency of use of night …

Modeling of the human head/neck system using rigid body dynamics
… member. The additional mass on the head due to Night Vision Goggles and Helmet Mounted Displays increases the vulnerability of the head/neck system to injury. To eliminate the need for human testing, computer simulations of biodynamic head and neck system response to large vertical accelerations …
