Download or read book Optical Characterization of Wide Field of View Night Vision Devices written by and published by . This book was released on 1999 with total page 7 pages. Available in PDF, EPUB and Kindle. 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.

This book was released on 2001 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Four Years of Night Vision Goggle Diopter Eyepiece Research and Field Studies with AFSOC Aircrew 2000 2004 written by and published by . This book was released on 2004 with total page 35 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.).

Download or read book The Visibility of Night Vision Imaging System Compatible Displays written by and published by . This book was released on 2001 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Panoramic Night Vision Goggle Update written by and published by . This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Operational test and evaluation of a first-ever 100 degree field of view (FOV) night vision goggle is currently underway at several locations. Testing is being conducted onboard F-15C, F-15E, and more recently F-117, C-5, C-130, CH-47D, and All-1 aircraft as well as with special operations ground personnel. In the near future, testing will include other ejection seat, transport, and rotorcraft platforms. Two configurations of the Panoramic Night Vision Goggle (PNVG) are being evaluated. The first version design (PNVG I) is very low in profile to fit underneath a visor and can be retained by the pilot in the case of an ejection. The second version (PNVG II) resembles the currently fielded 40 degree FOV AN/AVS-6 and F-4949 NVGs and is designed for non-ejection seat aircraft and ground applications. During flight evaluations, subjective questionnaires are being used to collect pilot ratings in order to compare capability of the 100 degree FOV PNVG to that of the 40 degree F-4949 across different operational tasks. The SA-SWORD technique is being used in order to produce situational awareness ratings for statistical analysis. The paper will discuss current findings and pilot feedback of the PNVG I system on F-15C and F-15E aircraft only.

Available in PDF, EPUB and Kindle. Book excerpt: Night vision goggles (NVGs) have been employed in a variety of aircraft for over 20 years. However, only recently has their application begun in fixed-wing fast movers. Research accomplished by the Aircrew Training Research Division of the USAF Armstrong Laboratory demonstrated the loss of NVG performance resulting from improper adjustments. This report describes correct adjustment procedures for the Aviator's Night Vision Imaging System, or ANVIS. The procedures described were developed so aircrews could take advantage of the adjustments available on the NVGs. Additionally, image descriptions are given to help aircrews evaluate NVG performance. Information on the proper equipment/ space needed for proper evaluation is also included. Adjustment procedures, Focusing procedures, AN/AVS-6, NVG. Alignment procedures, Interpupillary distance, ANVIS, Diopter, Night vision devices, IPD, NVD, Eye lane, Night vision goggles.
Download or read book The Dynacell and Focal Plane Concepts of Phototropic Systems Application to Ophthalmic Nuclear Flash protective Devices written by Robert W. Harries and published by . This book was released on 1962 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two concepts of phototropic systems application are presented in this report. These concepts, when considered individually or in combination, make possible the development of improved, directly or indirectly actuated, phototropic, ophthalmic, nuclear flash-protective devices. By the application of a phototropic filter at the focal plane of an optical system, the attenuation of the phototropic response due to distance is minimized. Using a renewable fluid filter, a concept is presented which offers the opportunity to use the more sensitive irreversible phototropic systems while still providing reversible characteristics. The operating characteristics of these concepts are presented along with some derived theoretical relationships.
