Visual acuity is often used to assess vision through image intensifying devices such as night vision goggles NVG's. Fewer attempts have been made to measure contrast sensitivity through NVG's. Such information would be useful to better understand contrast processing through NVG's under various stimulus conditions. In this study, computer-generated letter charts were used to measure contrast sensitivity through third generation NVG's for a range of letter sizes. The red phosphor of a standard color monitor proved to be an effective stimulus for third generation devices. Different night sky conditions were simulated over a 3 log unit range. The results illustrate the profile of contrast sensitivity through third generation NVG's over a range of night sky conditions.

They were built into adjustable gain Sentinel housings, red phosphor nvg, to allow you to dial each gain independently - I think this is absolutely key to the system.

Capable panoramic night vision has never been more within reach. Virtually all commercial sales are limited to a small number of dual tube units with the same degrees of vision. While quad tube units are nothing new, manufacturers have long restricted sales of these products to military and elite law enforcement. Although the technology is not illegal, sales restrictions and absurdly high prices have effectively barred many law-abiding Americans from ownership. When used panoramic devices make their way onto the market, hostile warranty and repair practices ensure an unpleasant experience. It is our view that civilians and regular law enforcement officers have a legitimate right to this technology — this is the primary reason behind our pursuit of the QTNVG. So why do I want more FOV? Short answer: To increase instantaneous availability of visual data.

The device enhances ambient visible light and converts near-infrared light into visible light which can be seen by the user; this is known as I 2 image intensification. By comparison, viewing of infrared thermal radiation is referred to as thermal imaging and operates in a different section of the infrared spectrum. A night vision device usually consists of an image intensifier tube, a protective housing, and may have some type of mounting system. Many NVDs also include a protective sacrificial lens, mounted over the front lens ie. The image produced by an NVD is typically monochrome green, as green was considered to be the easiest color to look at for prolonged periods in the dark. Night vision devices can be handheld but many are head-mounted and attach to helmets. When used with firearms, an IR laser sight is often mounted to the user's weapon. The laser sight produces an infrared beam that is only visible through an NVD and aids with aiming. These can be used in conjunction with weapon sights like rifle scopes or can be used as standalone sights; some thermal weapon sights have been designed to provide similar capabilities. Consequently, though they are commonly used by the military and law enforcement agencies, night vision devices are available to civilian users for a wide range of applications including aviation, driving, demining , etc.

Comparison of measurements through NVG's to measurements obtained without the device but at the same luminance and color distinguish between effects of luminance and noise on contrast sensitivity.

Ryan offered to ship a loaner set of Sentinels out to me for the shoot so I wouldn't be without. Abstract Visual acuity is often used to assess vision through image intensifying devices such as night vision goggles NVG's. It looks like it would be uncomfortable after a while.
