Night vision technology and night vision device: a technical review
Keywords: Night Vision, Infrared, Thermal Imaging, Image Enhancement, Night Vision Device, etc.
AbstractNight vision is the ability to see in low light conditions. Night vision is made possible by a combination of two approaches: sufficient spectral range and sufficient intensity range. Image intensification increases the amount of photons received from various natural sources such as starlight or moonlight so that a dimly lit scene can be viewed in real time. Active infrared night-vision systems include illuminators that produce high levels of infrared light, with the resulting images typically having higher resolution than other night-vision techniques. Thermal vision detects the temperature difference between background and foreground objects. Night vision device allows to see in no light or in low light at night time. Recently, night vision technology has become more widely available for civilian use. Night vision devices exist in many forms, from gunners to drivers and pilots.
