Progress of low level light video technology

As one of the key technologies to expand human eye's night visual perception, low level light (LLL) night vision technology has wide application in military and civilian fields. With the development of digital image processing technology, LLL video devices not only improve the night vision image quality through the image processing, but also provide a broad space for image information fusion with the infrared thermal imaging and the improvement of nighttime target detection/recognition, scene understanding ability and so on, become one of the important directions of current night vision technology both at home and abroad. This paper reviews the development of LLL video devices, analyzes the characteristics and development trends of electronic vacuum+solid LLL video imaging devices (such as ICCD/ICMOS, Electron Bombardment EBCCD/EBCMOS, etc.), all solid-state LLL video imaging devices (such as electron multiplying EMCCD, Extreme Low-Light CMOS, etc.), analyzes and discusses the development of LLL night vision technology combined with PHOTONIS LYNX program.
