This article deals with electro-optical means to see in nonvisible spectral regions and at very low light levels and to produce visible imagery. The wavelength regions covered range from UV (200 nm to 400 nm) to the thermal IR (8 µm to 14 µm). The visible spectrum band from 350 nm to 750 nm is covered only insofar, as very low light levels are concerned, that is, the use of image-intensifier systems is required. For every waveband, the physical properties of the scene and the atmosphere as well as the corresponding technologies to transform the scene under consideration into a visible representation are described. That includes optics, detectors, and cooling systems (if required). Performance parameters for the systems are described as far as available.
