Insight Technology, Inc proposes to design and deliver a proof-of-concept demonstrator of a helmet-mounted display system to support ground-based training for the Integrated Panoramic Night Vision Goggle (I-PNVG). The demonstrator will integrate with the physics-based visual simulation system (Night Vision Training System) of Image Intensification (I2) based night vision goggle imagery currently in development. The principle problem to be addressed is how to configure a head-mounted display that provides the increased field of view and approximate image characteristics (resolution, color, decay rates, etc.) of I-PNVG while at the same time providing the weight, center of gravity, and form, fit, and function characteristics of I-PNVG. Existing miniature CRT and flat-panel displays will be analyzed to determine which technology offers the best balance between image quality characteristics (resolution being top priority) and minimizing weight and center of gravity deviations from the actual goggle. The I-PNVG monocular will be modified to accept the selected display. Eyepiece optics will be designed to accommodate the display while providing a panoramic image consistent with that of I-PNVG. The modified monocular assemblies will be mounted to the actual I-PNVG pilot adjustment shelf to maintain commonality with form, fit, and function of the actual system.The development of a simulation-based helmet-mounted display that closely matches the form, fit, and function characteristics of the Integrated Panoramic Night Vision Goggle system will provide for realistic training in the safe and relatively low-cost simulation environment. The simulation system also will permit development of modified tactics, techniques, and procedures for a wide field of view night vision goggle in the ground-based simulation environment. Additional benefits will include the capability to develop and evaluate future I-PNVG enhancements in a simulation environment prior to in-flight use and evaluation of pilot performance improvements brought about by the wide field of view goggle
