Download or read book Search Effectiveness with the Starlight Scope and 7 X 50 Binoculars written by John Patrick Farrell and published by . This book was released on 1970 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The night operations program is concerned with problems in optimizing human performance in relation to night vision devices and related sensors. To further this research, experimentation has been directed toward enhancement of the performance of the combat soldier in night operations. The report describes an experimental evaluation or four passive night vision devices, and presents results of the assessment of operator performance with these devices in target detection and search tasks. Subjects were required to detect targets (soldiers or aggressor type silhouettes) presented in two modes. Responses were recorded electronically. Data obtained were analyzed to determine performance effectiveness with the two subject devices and the effects were studied of illumination (starlight, half moon, full moon), distance (50 - 300 meters), target mode (moving vs stationary), target exposure time (10, 20, 30 and 90 seconds), and their interactions on search performance.

Download or read book Improved Search Techniques with Passive Night Vision Devices written by James Huber Banks and published by . This book was released on 1971 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Night Operations Program is concerned with problems in optimizing human performance in relation to night vision devices and related sensors. In the furtherance of this research, studies are being conducted with passive night vision devices. Passive night vision devices developed for the Army have greatly increased night observation and target acquisition capabilities. Effectiveness of these devices, however, is highly dependent upon how and under what conditions they are used. The present study sought to determine whether new search techniques and procedures could increase the effectiveness of soldiers using passive night vision devices. The subjects (54 operators) using the Starlight Scope (SS) or the Night Observation Device, Medium Range (NOD) were given specialized search training and their training performance was compared with another group previously tested under the same conditions but without special training on search method and pattern.
Download or read book Night Vision Goggle Research and Training Issues for Ground Forces a Literature Review written by Jean L. Dyer and published by . This book was released on 1998 with total page 76 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.

Book excerpt: Quantum physics is the most fundamental -- but also the most baffling -- branch of science. Allowing for dead-and-alive cats, teleportation, antimatter, and parallel universes, as well as underpinning all of our digital technology, it's as important as it is mind-bending. This clear and compact book demystifies the strange and beautiful quantum world, and hence the nature of reality itself. Contents include: Schrodinger's cat, inside the atom, the particle zoo, the Higgs boson, Heisenberg's uncertainty principle, God playing dice, relativity, the Big Bang, dark energy and matter, black holes, the fate of the Universe, the Theory of Everything, quantum gravity, string theory, the multiverse, instant communication, quantum computing and cryptography, superconductivity, quantum biology, quantum consciousness, and much more. Written as a series of mini essays with 200 simple diagrams to help understanding, there can be no easier guide to this notoriously confusing subject. At last it's possible for non-specialists to understand quantum theory and its central role in the birth of the universe and the very existence of life.
Download or read book Introduction to Geometrical Optics written by Milton Katz and published by World Scientific. This book was released on 2002 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the culmination of twenty-five years of teaching Geometrical Optics. The volume is organised such that the single spherical refracting surface is the basic optical element. Spherical mirrors are treated as special cases of refraction, with the same applicable equations. Thin lens equations follow as combinations of spherical refracting surfaces while the cardinal points of the thick lens make it equivalent to a thin lens. Ultimately, one set of vergence equations are applicable to all these elements.The chapters are devoted to in-depth treatments of stops, pupils and ports; magnifiers, microscopes, telescopes, and camera lenses; ophthalmic instruments; resolving power and MTF; trigonometric ray tracing; and chromatic and monochromatic aberrations. There are over 100 worked examples, 400 homework problems and 400 illustrations.First published in 1994 by Penumbra Publishing Co.
