night vision device

Any electro-optical device that is used to detect visible and infrared energy and provide a visible image. Night vision goggles, forward-looking infrared, thermal sights, and low-light level television are night vision devices. Also called NVD. See also forward-looking infrared; night vision goggles(s).

In the cardiovascular literature, a technique was described for inserting an angioplasty balloon catheter along the drain tract and into the retained drain lumen under image intensification. The balloon is then inflated within the drain lumen creating an interference fit.
OPERATIVE TECHNIQUE: After taking consent and following strict pre-op instructions under general anaesthesia Closed reduction was done as described above under image intensification. and after achieving reduction the elbow is secured in hyper flexion.
Later, in the 1980s technology developed in the medical industry that combined image intensification with fluorescent screens and analog cameras was adapted to field inspection of in-service pipelines, thereby, creating a system capable of cost-effectively inspecting long lengths of a pipeline to locate and evaluate areas of localized corrosion.
Analysis of implantation-induced nail deformation and roentgen morphometric studies as the principle for an aiming device for distal interlocking nailing without roentgen image intensification [German].
Armed with the latest in image intensification and other target acquisition technology, American soldiers have an edge in missions at night or in other low-visibility situations.
In the past, the best nighttime detection measure was to combine a handful of different technologies--increased perimeter lighting, perimeter surveillance cameras and possibly infrared illumination or image intensification ([I.sup.2]) technologies.
The Enhanced Night Vision Goggle (ENVG) will be a helmet-mounted, passive device for the individual soldier that incorporates image intensification and long-wave infrared sensors for night operations.
ITT Industries Night Vision of Roanoke, VA, and Raytheon Co., Dallas, TX, have announced a strategic teaming agreement by which the two leaders in image intensification and thermal imaging technologies will develop and produce night vision sensor fusion technology.
Using image intensification or infra-red goggles, they can turn darkness into daylight.
During fluoroscopy procedures, the film badge normally should be worn at the level of the collar, outside the lead apron.[3] Many studies have indicated that during image intensification fluoroscopy, the neck area receives between 10 and 20 times more radiation exposure than the trunk, which is protected by the lead apron,[1,2] By wearing the film badge under the lead apron, you inadvertently create a false sense of security due to inaccurately low badge readings.
The two companies have collaborated previously, with Exelis' state-of-the-art image intensification technology used by NIRF Imaging as a key component in a proprietary medical imaging technology based on Near InfraRed Fluorescence (NIRF) and micro-doses of non-radioactive dye.
