Active infrared night-vision combines infrared illumination of spectral range 700–1,000 nm (just over 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. [ 13 ]

The AN/PSQ-20 Enhanced Night Vision Goggle (ENVG) is a third-generation passive monocular night vision device developed for the United States Armed Forces by ITT Exelis. It fuses image-intensifying and thermal-imaging technologies, enabling vision in conditions with very little light. The two methods can be used simultaneously or individually.
