Book excerpt: 7026(*NIGHT WARFARE, *EYEGLASSES), EFFECTIVENESS, NIGHT VISION, COMBAT SURVEILLANCE, SPECIFICATIONS, SIMULATORS, TEST METHODS, RELIABILITY*GOGGLES, *NIGHT VISION, NIGHT DRIVINGThe present report addresses the overall utility of the night vision goggles. Military effectiveness of the goggles over the unaided eye for night driving, close-order operations, patrol, and combat surveillance was evaluated by field experimentation. Identification of optical, electro-optical, and human-related factors was done through laboratory simulation and bench-test evaluations. Alternative approaches, as well as electro-optical specifications for individual night vision aides, were considered and evaluated. The 40 degrees FOV Night Vision Goggles provide a dual (passive-active), open-hatch, night-driving capability for armored vehicles. (Author Modified Abstract).

Book Synopsis Simulating Night Vision Goggle Effects in a Virtual Environment by : Robert J. Pleban
Download or read book Simulating Night Vision Goggle Effects in a Virtual Environment written by Robert J. Pleban and published by . This book was released on 2002 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This research examined the capabilities of virtual environments to simulate night vision goggle (NVG) effects. Different solutions for simulating NVG images were assessed. Two conditions simulated NVGs but used different software approaches. Two additional conditions simulated unaided night environments that required soldiers to wear NVGs. Four-man infantry teams conducted urban operation missions under each condition. Objective assessments were obtained on the number of events correctly detected and the average time required to detect an event. Subjective assessments of task difficulty and image fidelity were also made. No significant differences were found across night conditions for either event detection or time. Significant differences in task difficulty ratings occurred for movement, visual detection, and maintaining situation awareness. In general, tasks were more difficult to perform while wearing the NVGs compared to simulated versions of NVG images. Soldiers also ranked the conditions involving actual NVGs as more realistic. The unique contribution of virtual environments for night operations training may be at the entry level. However, specific image fidelity issues associated with the use of NVGs in simulated unaided night environments must be addressed if this approach is to be used as an effective training medium."--Stinet.

Book excerpt: This document addresses the potential use of night vision goggles (NVG's) by the civilian rotorcraft community. Key issues analyzed are the advantages and limitations of using NVG's in civilian rotorcraft operations, safety factors surrounding NVG use, and pilot qualification/training requirements. Background information on NVG equipment design, characteristics, types, and associated aircraft requirements/modifications are also presented in the context of civilian use. These issues are then related to the existing FAA regulations concerning night flying operations. Pilots, engineers, and aeromedical experts from the uniformed services, as well as several civil proponents who have had extensive experience with NVG's were interviewed. Their experiences, insights, and recommendations are incorporated into the text. All those with previous NVG experience agreed that despite the limitations, they would prefer flying at night with NVG's available and that NVG's reduce stress and increase situational awareness in the cockpit at night. This investigation concludes that the civil use of NVG's as an aid during en route and certain terminal operations can increase safety, enhance situational awareness, and significantly reduce the pilot workload and stress normally associated with flying at night. At the same time this investigation highlights that a number of key safety issues, unique to the civilian pilot community, still need to be resolved. A follow-on flight evaluation and simulation effort are envisioned to address these issues. Rotorcraft, Visionics, Night vision goggles, Image intensification, Night flying.

Download or read book Night Vision Goggle Research and Training Issues for Ground Forces written by Jean L. Dyer and published by . This book was released on 1998-05-01 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: A review of the night vision goggle (NVG) literature published over a 30-year period was conducted to identify NVG training issues that should be addressed to enhance the performance of ground forces. First-, second-, and third-generation image intensification devices are covered. Although the focus is on ground forces, research that addressed aviation issues is also included. The review documents bow soldier performance has improved from advancements in image intensification technology as well as from concerted efforts to address some long-standing training problems. Training research and development issues identified are: determining techniques to train soldiers on NVG technology and its application to night tasks, how to train soldiers to integrate NVGs with other equipment, training to enhance distance estimation abilities of soldiers when using NVGs, and training to improve mounted and dismounted navigation skills with NVGs. Attention must also be paid to developing training techniques that will enable soldiers to overcome the learning plateaus and human factors problems with NVGs so they become truly skilled at night with NVGs.

Download or read book Human Factors Evaluation of Night Vision Goggle Design: written by and published by . This book was released on 2004 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study utilizes the repertory grid technique to elicit & determine the desirable characteristics of night vision goggle design from the perspective of soldiers who are familiar with night vision goggle & night-time terrain traverse operations. Four types of goggles, selected based on their different engineering designs, were tested by 31 soldiers in exercises on four different types of terrain: dense woods, open woods, open country, and urban town. Content analysis of the 83 concepts or criteria elicited from the soldiers were converged & mapped onto 25 night vision goggle concept categories. Further cluster analysis revealed three meaningful clusters of concepts, namely functionality, comfort, and usability. Application of the repertory grid identified meaningful & relevant criteria to evaluate the goggles; allowed for the formulation of a path model for a general equipment evaluation process; indicated relative design strengths or weaknesses of the goggles tested; and led to a recommended design for a dual configuration hybrid night vision goggle for further testing & development.
Book Synopsis Distance Estimation Training with Night Vision Goggles by : Jack D. Reising
Download or read book Distance Estimation Training with Night Vision Goggles written by Jack D. Reising and published by . This book was released on 1994 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aircrews have reported significant problems in depth perception and distance estimation with night vision goggles (NVGs). The purposes of this experiment were to develop a methodology for quantifying distance estimation abilities with NVGs and to examine the value of a simple training procedure as a means of reducing errors. Absolute distance estimates were obtained from eight male aviators using Aviators Night Vision Imaging System (ANVIS) AN/AVS-6 NVGs before and after exposure to a set of known distances. The results revealed that distance estimates were linear and significant reductions in errors and variability followed exposure to the training procedure. The results are discussed within the context of previous research. Issues for future research are addressed. Distance estimation, Night vision goggles, Training.

Download or read book Extended Use of Night Vision Goggles: An Evaluation of Comfort for Monocular and Biocular Configurations written by and published by . This book was released on 1997 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forty-four military participants were tested in a field experiment to compare the relative discomfort experienced when monocular versus biocular night vision goggles (NVGs) were worn for an extended period of time. Participants traversed wooded terrain to reach various stations where they performed a variety of military and field craft tasks. The total test time was 4 hours. The participants rated their psychological and physiological feelings of discomfort at the completion of the test and again the following evening. Objective measures of NVG optical adjustments were also recorded. The participants who wore the biocular goggle reported a higher incidence of tight neck muscles than did the participants who wore the monocular goggle. However, no other significant differences in discomfort were found that could be attributed to the ocular configuration of the goggles. All participants complained about discomfort from the head harness.

This book was released on 2018-07-02 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using laboratory simulations, visual performance was measured at luminance and night vision imaging system (NVIS) radiance levels typically encountered in the natural nocturnal environment. Comparisons were made between visual performance with unaided vision and that observed with subjects using image intensification. An Amplified Night Vision Imaging System (ANVIS6) binocular image intensifier was used. Light levels available in the experiments (using video display technology and filters) were matched to those of reflecting objects illuminated by representative night-sky conditions (e.g., full moon, starlight). Results show that as expected, the precipitous decline in foveal acuity experienced with decreasing mesopic luminance levels is effectively shifted to much lower light levels by use of an image intensification system. The benefits of intensification are most pronounced foveally, but still observable at 20 deg eccentricity. Binocularity provides a small improvement in visual acuity under both intensified and unintensified conditions. Bradley, Arthur and Kaiser, Mary K. Ames Research Center ...

Download or read book Formulative Evaluation Study of a Prototype Near-Infrared Projection System: Night Vision Goggle Study written by and published by . This book was released on 1991 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: U.S. Army Aviation relies upon image intensifiers, such as night vision goggles (NVGs), for night nap-of-the-earth (NOE) flight. During initial flight training, OH-58 student pilots are expected to apply academic knowledge of NVG use in flight after limited review. To facilitate OH-58 students' transition to NVG flight, researchers projected images through a prototype near- infrared (IR) video projection system. Helicopter pilot students received hands- on experience with the AN/PVS-5A NVGs, which are compatible with the projection system's output range. Instructor pilots rated OH-58 students' flight performance throughout the night/NVG phase of instruction. A strong positive effect on students' confidence (increase) and anxiety (decrease) levels were observed. No difference in flight performance was observed between matched pairs (experimental vs. control) of students. Additional research is planned in the areas of safety of flight, terrain navigation, special operations, mission planning, and threat recognition.

Download or read book Interlaboratory Study (ILS) of the Standard Test Method for Measuring the Night Vision Goggle-Weighted Transmissivity of Transparent Parts written by Alan R. Pinkus and published by . This book was released on 1998-03-01 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are several ASTM Standards that address light transmissivity through transparencies (ASTM Standards F 1316-90D and 1003-61) in the visible spectrum (400 through 700 nm). However, night vision goggles (NVGs) are now being used in aircraft and other applications (e.g., marine navigation, surveillance, personnel carriers) with increasing frequency. These devices amplify both visible and near-infrared (NIR) spectral energy. A transparency may have excellent visible transmissive characteristics but could have poor NIR transmissivity. Overall visual performance (acuity) can be degraded if the observer uses the NVGs while looking through a transparency that has attenuated transmissivity in the NIR region (Pinkus and Task, 1997, see Appendix A). ASTM P94-02, Standard Test Method for Measuring Night Vision Goggle-Weighted Transmissivity of Transparent Materials (see draft in Appendix B) addresses this issue.
