Book excerpt: An advanced night vision device, the Panoramic Night Vision Goggle (PNVG), presents the wearer with a large horizontal field of view (100 degrees) by combining the output from multiple image intensifier tubes. This significantly complicates the testing and evaluation of this state-of-the-art device. Current tests were considered insufficient and required modification to fully characterize conventional night vision device parameters. In addition, new tests were required to characterize parameters unique to the current PNVG design. This paper discusses the optical performance testing of the PNVG, concentrating primarily on four night-vision-device parameters: field of view, visual acuity, eyepiece diopter setting, and image discontinuity.
