Night vision devices

Caesium compounds find application in pyrotechnic formulations to provide a source of near IR radiation for night vision devices which are widely used as electro-optical equipment for surveillance, searching and tracking in the near IR(NIR) region of the electromagnetic spectrum. Lohkamp suggested the use of... 

The band gap decreases with increasing atomic number of the elements, so that materials such as cadmium mercury telluride Cd Hg/Te, in which a small proportion of the cadmium positions are taken by mercury, become conducting on exposure to infrared light and are used in heat seeking and night vision devices. 

Some of the present industrial uses of diamond coatings include cutting tools, optical windows, heat spreaders, acoustic wave filters, flat-panel displays, photomultiplier and microwave power tubes, night vision devices, and sensors. Because its thermal conductivity and electrical insulation qualities are high, diamond is used for heat sinks in x- ray windows, circuit packaging, and high-power electroific devices. Moreover, the high chemical stability and inertness of diamond make it ideal for use in corrosive environments and in prosthetic devices that require biocompatibility.

Very little IR (Infra Red)radiation is emi-tted upon firing.This protects the firer s position from being discovered at night by an observer using an IR viewer. (See "Night Vision Devices"in PMA Vol.2 i 2, page 48). 

MCP s can be made in a variety of geometries, although normally they are in the form of rectangular or circular flat wafers whose thickness is 40 to 120 times the diameter of the glass tubes. A number of manufacturers now sell MCP s either mounted or unmounted the most readily available are 1 inch diameter MCP s with 40 1 channel length to diameter (L / d) ratio manufactured for military night vision devices. Some... 

The M45 will replace the Army s M49 Mask System. The mask provides the required CB protection without the aid of forced ventilation air while maintaining compatibility with rotarywing aircraft sighting systems and night vision devices. See FM 3-5 for filter exchange rates. 

Infrared - Infrared radiation is radiation with wavelengths between 760 nanometers -1 millimeter. Most of the lasers and night vision devices used by the Army operate in this region. Investigational New Drug - A drug that has not received full FDA approval and can only be used with written approval of the patient. 

The mask is compatible with shoulder-fired weapons, night-vision devices, and sighting devices. A variety of accessory items is available, including the Ml waterproof bag, the M4 winterization kit, the M6A2 hood, the M15A1 carrier, and optical inserts and outserts. This series of mask is currently being replaced by the M40 protective mask.14,15 Mask, Chemical-Biological Field, M40... 

Speaking of military fuel cell applications, we must first point out the following. Most versions of fuel cell-based power plants are of ambivalent utility they are just as good for civil as for military purposes. Thus, the stationary power plants of different sizes used for unintermptible emergency power supplies for military objects such as forts, command centers, radar stations, and the like do not differ in any way from similar power plants for civil use in hospitals, telecommunications installations, computer centers of banks, and so on. Power plants for automotive land and water-bound means of transport are equally good for civil and for military vehicles. This is true, even more directly, for power sources intended to supply portable equipment. A lower volume and weight of all equipment carried by soldiers in combat (e.g., as a means of communication, as a means of orientation, as night-vision devices) is a very important point for land forces.

Because charge-coupled devices are sensitive to infrared light, they can be used in some solid-state night-vision devices—and some commercial cameras and video cameras have night-vision capability. 

Thermal imaging has been made possible with improved sensitivity and light amplification and also creates images using infrared wavelengths that are emitted as heat. Not all night vision devices are able to detect thermal energy. 

Thermal forward-looking imaging (FLIR) devices are installed on vehicles and helicopters. Night vision devices are available to personnel for survival purposes even in a downed aircraft. This technology has continued to be employed in weapons-aiming devices. Data collection and communications technology have been added to some night vision devices in order to improve military communication and reconnaissance. 

Scientific Research. Scientists use night vision devices to study nocturnal animals and other phenomena that might not otherwise be visible to the human eye. This has opened up a new area of study for wildlife biologists. In some parks, night vision technology is used to study wildlife and vehicle collisions in order to determine ways to reduce these incidents, which are dangerous to both humans and animals. 

The invention of night vision devices has led to an industry of device manufacturers and researchers.
