Using a Night Vision Device

It's difficult to see in the dark. Unless there's some light peeking in through the window or from under a door, our vision is compromised. If we wait a little while, our night vision kicks in, allowing us to see somewhat better. It's not enough that we can read in the dark, but it should be enough to keep us from stumbling into furniture or tripping over the carpet. Sometimes though, our human night vision isn't enough and we need a little help.

That's where technology kicks in. Thanks to science we can use night vision to do all sorts of things. With the proper equipment we can hunt, take pictures or even fight wars in the dark. We can also perform surveillance and search and rescue missions.

Here's how it works: Your night vision product will take existing light and amplify it through an objective lens, which then focuses on an image intensifier. A photocathode located inside the intensifier converts the photon energy into electrons. The electrons in turn strike a phosphor screen creating a viewable image. In reality it looks like you're watching television on a green screen.

Atmospheric conditions can affect night vision. For instance, if it's cloudy, foggy, or overcast, night vision can be compromised. The clearer the night, the farther one will be able to see with night vision technology. It should also be noted that night vision shouldn't be magnified, as light is lost during the magnification process making it more difficult to see.

Night vision devices include:
- Cameras
- Binoculars
- Scopes for firearms
- Goggles

If you think that using a night vision device on a frequent basis might be harmful, you couldn't be more wrong. Night vision products are no more harmful than a television or movie screen. It doesn't emit radiation or other harmful rays and there's no reason for it to cause blindness.

Advanced Nightvision Binoculars 3.5x40 $659.99 Yukon Advanced Optics? engineers kept versatility and comfort in mind when creating the Viking series of night vision binoculars.

It comes with removable, individual, collimated, doubler lenses, and can be transformed to a 2x24 unit by removing the 40mm lenses. The Viking makes use of a single built-in PULSE infrared illuminator for added image clarity in total darkness. The PULSE system utilizes quick infrared energy bursts that pierce the darkness further to increase distance, visibility and image quality. The PULSE IR System provides the highest level of infrared illumination without significant battery drainage. The same ?pulsing? frequency that is invisible to human eyes infiltrates longer distances due to the Infrared Illuminator?s quick energy bursts.

Advanced Nightvision Binoculars 2x24 $479.99 The Viking LT 2x24 night vision binocular has a magnification of 2x and an objective lens of 24mm. The unit?s eye relief of 12 mm allows for comfortable viewing while the 400 m range of detection makes this unit perfect for long distance viewing. The Viking LT 2x24 provides clear viewing in total darkness by utilizing a single built-in IR illuminator with a range of 150 m. Throw the ergonomically-designed, rubberized body around your neck for a long expedition; the lightweight (21 oz.), compact (6.9 x 4.8 x 2.8 in.) unit is surprisingly comfortable, making your viewing experience that much more enjoyable. Like all Viking models, the LT utilizes Yukon?s newly designed Eclipse lens cap system, which removes lens cap hassles, dual eye diopter adjustment with central focusing, and a wide field of view (30 degrees). All image intensifier tubes are extremely light sensitive and can be destroyed by bright lights; however the Viking LT 2x24 remedies this problem by including Yukon?s exclusive Eclipse lens cap system. These lens caps include a pinhole to protect the unit from bright light, but still allow the user the option of daytime use. Yukon?s exclusive Eclipse lens cap system not only protects the unit from bright light, it also saves users from many irritations. Everyone knows the hassles associated with binoculars? lens caps - they get lost or tangled, but without them the lenses become dusty or scratched up. The Eclipse lens cap system features flip-top lens covers that can be flipped up to fit against the binoculars? body and rotated to ensure that they are out of the viewing field. Also, the covers can be taken off all together. In addition to the Eclipse lens cap system, the water resistant Viking utilizes a soft, one-piece eyecup to prevent external light distortion and light leakage from the device, allowing the user to remain hidden in the night. The Viking makes use of a built-in PULSE infrared illuminator for added image clarity in total darkness. The PULSE system utilizes quick infrared energy bursts that pierce the darkness further to increase distance, visibility and image quality. The PULSE IR System provides the highest level of infrared illumination without significant battery drainage. The same ?pulsing? frequency that is invisible to human eyes infiltrates longer distances due to the Infrared Illuminator?s quick energy bursts.

Automated Incident Detection in Surveillance Systems $113.11 The importance of public security cannot be overemphasized in todays world. Surveillance systems consisting of extensive camera networks now have many applications. The London Underground has 9000 cameras, with each staff required to monitor as many as 60 at a time. This presents a significant scope for automation. Processing a sequence of images from a network presents challenges in terms of deciding upon the feature set to be extracted, and the appropriate choice of algorithm. We investigate methods based upon principal component analysis and nearestneighbor distances to propose a system of automated intruder detection in surveillance systems and suggest new applications in Bangladesh of such systems.

The Watchers: The Rise of America's Surveillance State $3.99 In 1983, John Poindexter, President Regan's national security advisor, realized that the United States might have prevented the massacre of 241 Marines in Beirut if intelligence agencies could have analyzed in real time the data they had on the attackers. What ensued over the next quarter-century were ambitious government efforts to create an intelligence-gathering system of unprecedented scope and sophistication. But despite the billions of dollars spent, the result is a supreme irony: While catching the terrorists hasn't become any easier, spying on the rest of us is now routine. Based on exclusive access to key government sources, this is the chilling history of our nation's evolution into a surveillance state.
