Infrared low-light night vision deviceInfrared low-light night vision technology
Infrared low-light night vision device is a product that combines low-light night vision and infrared night vision, integrating the functions of low-light night vision and infrared night vision. The latest digital enhanced infrared low-light night vision device is a high-sensitivity high-resolution CCD array and a new lightweight TM software technology used in digital enhanced devices, 5 times magnification and long-distance viewing range - up to 600 meters, Image clarity and brightness have also been greatly improved, and images delivered to the monochrome LCD display are clear and sharp throughout the viewing field. The device is capable of use in situations that fluctuate over a wide range of natural nighttime lighting. To observe in the middle of the night with cloudy moon, you can use the adjustable infrared illuminator. Wave lengths up to 940 nm - infrared light "invisible" to observers, even with units used in active mode. The built-in video output allows transferring the image to a monitor or TV for long-term fixed-time viewing, video recording, and external recording equipment.
Features and uses of infrared low-light night vision device
Features: Now the infrared low-light night vision device is generally light in size, easy to carry, and convenient for night observation. It uses the low-brightness night sky, starlight, moonlight, atmospheric glow and other natural light reflected by the night target to enhance and magnify it to thousands to hundreds of thousands of times. , so that it is suitable for human eyes to observe, reconnaissance, aiming, vehicle driving and other battlefield operations at night.
Uses: Observation, Hiking, Camping, Caving, Commercial and Amateur Fishing, Boating, Law Enforcement, Search and Rescue, Surveillance.
The infrared low-light night vision device integrates two technologies, and has two functions of infrared night vision and low-light night vision.
Night vision technology is a photoelectric technology that realizes night observation by means of photoelectric imaging devices. Night vision technology includes low-light night vision and infrared night vision.
Low-light night vision technology, also known as image intensification technology, collects and intensifies the existing light by focusing the light on the image intensifier through the eyepiece. Inside the intensifier, a photocathode will be "activated" by light and convert photon energy These electrons are accelerated by an electrostatic region located inside the intensifier, and then hit the phosphor surface screen (like a green TV screen), forming an image visible to the human eye. Through the acceleration of electrons, the brightness and image clarity are enhanced. The new digital night vision device adopts the 2nd and 3rd generation image intensifier tubes, the edge of the field of view is no longer blurred, and it works very well in complete darkness and long-distance use. Low-light night vision device is currently the night vision equipment with the largest production volume and equipment in foreign countries and the most widely used. It can be divided into direct observation (such as night vision observer, weapon sight, night driving device, night vision glasses) and indirect observation. Observation (such as low-light television) two.
Infrared night vision technology is divided into active infrared night vision technology and passive infrared night vision technology. Active infrared night vision technology is a night vision technology that implements observation by actively illuminating and using the infrared light reflected by the target to reflect the infrared source. The corresponding equipment is an active infrared night vision device. Passive infrared night vision technology is an infrared technology that realizes observation by means of the infrared radiation emitted by the target itself. It detects the target according to the temperature difference or thermal radiation difference between the target and the background or each part of the target. Its equipment is a thermal imager. Thermal imagers have unique advantages different from other night vision devices, such as being able to work in fog, rain, and snow, having a long range, being able to identify camouflage and anti-jamming, etc., which have become the focus of the development of foreign night vision equipment, and Will replace the low-light night vision device to a certain extent.
