Most people have seen night vision in television or movie, some hunters even have direct experience with night vision. But many people do not know what is the difference between the different breeds. There is a night vision riflescope with digital night vision and Night Vision Monucular and hunter hunting on the gun. The working principle of a night-vision device is that a traditional night-vision device generally uses infrared light, starlight or moonlight that can not be seen directly by the human eye to observe and aim at the target by enhancing the visible image visible on the fluorescent screen as an intensifier. night vision monucular This type of light does not work in a completely dark environment and is therefore also known as a low-light night-vision device, generally equipped with an image-intensification tube (IIT). Instead of being equipped with phototransistors, the new digital night vision devices use charge-coupled devices (CCD) or complementary metal-oxide-semiconductor (CMOS) and microdisplays imaging , Work in total darkness, the most technologically advanced night vision device available today. The Night vision riflescope is mainly mounted on a shotgun or a military gun, Active infrared night-vision combines infrared illumination of spectral range 700-1,000 nm (just below the visible spectrum of the human eye) with CCD cameras sensitive to this light. The resulting scene, which is apparently dark to a human observer, appears as a monochrome image on a normal display device. Because active infrared night-vision systems can incorporate illuminators that produce high levels of infrared light, the resulting images are typically higher resolution than other night-visiontechnologies.
