Research progress of true color digital night vision technology

Abstract

The color information in the true color low light level night vision image is the true restoration of the visible light color information reflected by the scene itself. Compared with the gray-scale level image and the false color image, it can obtain more abundant image information, which is more in line with the observation habit of the human eye and reduce the fatigue of the human eye. Under the background of information war, aiming at the multi-functional, all-weather, information sharing and transmission characteristics of new type of low light level equipment for single soldier, the requirements of digitalization, high integration and low power consumption are put forward for the true color low light level night vision technology. In this paper, the research progress of real color digital night vision technology is reviewed: firstly, the classification of color night vision technology is introduced; then, the foreign true color digital night vision products represented by French photonis company, Japanese komamura company and American SPI Infrared company are summarized, included the technology route and development level of the true color digital night vision technology; finally, three issues that need to be considered in the realization of low light level night vision true color technology are proposed.
