Night vision is a field of research that focuses on the development of technology and devices that enable individuals to see in low-light or nighttime conditions. This technology typically amplifies existing light sources or uses infrared radiation to enhance visibility in darkness. Night vision technology is commonly used in military, law enforcement, and surveillance applications, as well as in certain civilian and recreational settings such as hunting and wildlife observation. Researchers in this field work to improve the sensitivity, resolution, and overall performance of night vision systems, as well as to reduce their size, weight, and cost.
