Download or read book Night Vision Goggle Field-Expedient Visual Acuity Adjustment Procedures: Initial Experiment written by and published by . This book was released on 1996 with total page 46 pages. Available in PDF, EPUB and Kindle. Book excerpt: The third-generation image intensification technology in night vision goggles (NVGs) used by ground forces provides at best 20/40 or 20/45 visual acuity. These acuity levels cannot be achieved unless soldiers adjust their NVGs properly. Documentation available to soldiers does not address optimum adjustment techniques developed by the aviation community nor does it address what can be used in the field to achieve a good setting. We examined the effectiveness and utility of 15 different objects commonly available to soldiers to determine which provided the best visual acuity readings with the AN/PVS-713 NVGs. After training and practice acuity improved by 25% over the baseline assessment. No large differences in readings occurred among the objects. However, a more definitive picture emerged when the average readings were combined with measures of variability and soldier preferences. The initial recommendation is to use one of the following objects for NVG adjustment: trec trunk, vehicle, vehicle trail, stars, blue chem light, or an infrared chem light. Not recommended are bright and/or red light sources, white paper, and trees silhouetted against the night sky. Problems in assessing acuity with NVGs are also discussed.

Download or read book Visual Acuity Versus Field-of-View and Light Level for Night Vision Goggles (NVG). written by Harry L. Task and published by . This book was released on 1994 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parameters typically used to characterize night vision goggles (NVG) are visual acuity (resolution) and field-of-view (FOV). An increase in FOV is accomplished by providing higher magnification of the image intensifier tube. However, increased magnification means that the pixels will subtend a larger angle, thus leading to lower NVG visual acuity. An inverse relationship between visual acuity and field-of-view is expected based upon this optical/geometrical relationship. This relationship should be examined as production of NVG resolution quality increases. A trade-off study examining FOV and resolution was conducted with three observers having 20/20 corrected Snellen acuity. The NVGs had fields-of-view of 40, 47, and 52 degrees, respectively. Five levels of ambient scene illumination (corresponding to output luminance levels of 0.01, 0. 03, 0.08, 0.26, and 1.4 ft-L) were provided by a 2856K light source. The targets used in the study were 95+% contrast square wave targets ranging in size from 45 cycles/degree to 5 cycles per degree. A walk-back method of adjustment was employed. The results indicate that the geometric relationship between field-of-view and visual acuity is valid. Night vision devices, Visual acuity, Night vision goggles.

This book was released on 1993 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Night Vision Programs Office of the Aircrew Training Research Division, Armstrong Laboratory, responded to a request from the 422nd Operational Test Squadron at Nellis AFB to conduct the ground testing portion of their A-10 Night Vision Goggle (NVG) special project. Evaluations were conducted comparing the performance of four different NVGs under both laboratory and representative operational conditions. The performance of the F4949 'Super ANVIS' was superior to that of the other NVGs tested. Additionally, a comparative study was conducted evaluating the impact of two different windscreens on NVG image quality. The new windscreen allowed the transmission of more energy usable to the NVGS, thus enhancing image quality over that possible with the old windscreen ...

Download or read book Training Lessons Learned on Sights and Devices in the Land Warrior (LW) Weapon Subsystem written by Jean L. Dyer and published by . This book was released on 1999 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The Land Warrior (LW) system is the Army's future system for the individual soldier. The LW consists of five subsystems, with the weapon subsystem the focus of the training research. The training of two platoons in preparation for a LW operational test was observed. Four sights and devices were trained (the close combat optic, two aiming lights, and the thermal weapon sight), plus a bore light. The training adequately prepared the soldiers to qualify on the M4 carbine with the close combat optic and the thermal weapon sight. Qualification standards were extremely difficult to achieve with the aiming lights on the M4, due to environmental conditions typical of Army ranges, not to lack of firer expertise. A standardized technique for boresighting all the devices was developed. Diagnostic skills needed by trainers and soldiers to effectively hit targets with each device were identified. The findings have immediate applicability to the Army, as the devices are currently being fielded. The report describes what contributes to quality training on the devices, and what should be integrated into marksmanship programs of instruction, technical manuals, and the training and doctrine literature." -- Stinet.
