Book Description
For over twenty years, the Crew System Interface Division (HEC; www.hec.afrl.af.mil) of the Air Force Research Laboratory (AFRL), located at Wright-Patterson Air Force Base OH, has advanced night vision technology. This technology includes investigations into visual acuity through night vision goggles (NVGs), night vision imaging system (NVIS) cockpit lighting compatibility, wide field-of-view night vision devices, NVG measurement methodologies, plus human factors and aircraft integration issues. This document is a compilation of the complete text of selected publications and reports produced by AFRL/HEC addressing these various areas of night vision technology. It also includes a listing of relevant patent abstracts and a bibliography of other Division publications related to night vision technology.

Book Description
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.

Book Description
After preliminary operational testing of the Honeywell F-16 Common Configuration Implementation Program (CCIP) Common Color Multi-Function Display (CCMFD), a display intended to incorporate color into night vision imaging system (NVIS) compatible cockpits, some observers felt that the CCMFD did not present video with the same level of detail in NVIS mode as seen in daytime mode. It was also believed that the CCMFD might be interfering with vision through night vision goggles (NVGs), noticeably reducing visual acuity. In addition, pilots wearing NVGs felt that the display was too dim to easily read under certain conditions after prolonged NVG exposure. To address these concerns, the Air Force Research Laboratory, Human Effectiveness Directorate, AFRL/HECV, ran a series of tests with the assistance of the F-16 SPO, the Air Force Reserve and Air National Guard Test Center (AATC/DO), Honeywell, and Lockheed-Martin, to assess the NVIS compatibility and legibility of the CCMFD in its NVIS mode. This paper documents both the results of this testing and an analysis of subjective comments made by observers during a demonstration of the display under the suspect conditions noted by AATC/DO.

Book Description
This historical survey was undertaken as a case study in Air Force research activities as conducted at the Aeronautical Research Laboratory, Wright-Patterson Air Force Base, Ohio. While it primarily concerns the work on Project 7072, Research on the Quantum Nature of Light, at one Air Force laboratory, the study may also be construed as throwing some light on the problems and achievements of Air Force research in general.

Book Description
United States Air Force aircrews are some of the most skilled and highly experienced night vision goggle (NVG) users in the world. Beginning in the 1990s, the use of AN/AVS-9 (F4949) allowed aircrews to have continuously adjustable eyepiece diopter settings. However, continuously adjustable eyepiece settings are not in the design of the newest NVG that is in the transition phase of being fielded. The Panoramic Night Vision Goggle (PNVG) has a 95-degree horizontal field-of-view, achieved with two channels per ocular with an image intensifier each. The first three studies reported on in this publication were performed to help determine what fixed diopter setting of the eyepiece would work for most aircrew. The surveys were conducted with AFSOC aircrew members at several Special Operations Squadrons in Ft. Walton Beach, Florida. The first study surveyed 95 aircrew to determine the range of diopter settings they were using. A second study addressed how consistent 18 highly trained aircrew were at preflight setting of their goggles. The third study addressed how 90 aircrew would tolerate a fixed-focus eyepiece set at either -1.0D or -0.50D. In another study, aircrew members gave a favorable response to the use of snap-on lenses, so the authors proceeded to examine how many snap-on lenses would be necessary for the majority of the user population. It was determined that the majority of aircrew could work with a total of 3 diopter settings: -0.25D, -1.0D, and -2.0D. It also was determined that custom snap-on lenses could be made for the few crew members who could not work with the three choices. For some of these individuals, the lenses needed to be refracted. A final study was designed to evaluate NVG visual acuity and subjective ratings for a range of diopter settings, including user-selected and three fixed settings of -0.25D, -1D, and -2D. The median user-selected setting was -1.25D and ranged from +0.5D to -3.5D. (multiple tables, figures, and refs.).

Book Description
In an effort to incorporate color displays into night vision imaging system (NVIS) compatible cockpits, the F-16 System Program Office through Lockheed Martin Tactical Aircraft Systems, requested Honeywell's Aerospace Electronic Systems division to design and construct a prototype color multifunction display. Observers indicated during preliminary operational testing that this display, when configured in NVIS mode, did not present video with the desired level of detail and was too dim to easily read under certain conditions. Testing showed that the Honeywell display met the existing MIL-L-85762A NVIS B radiance compatibility criteria required by contract. However, during a demonstration of the display, F-16 pilots with night vision goggle experience insisted that the display's visibility was marginal, reiterating their concerns on display legibility. this paper discusses the testing of the color multifunction display and potential factors that could be limiting the visibility of the display, in particular, the size of the characters displayed and the luminance levels specified in MIL-L-85762A.
