low light level television , LLLTV (abbreviation)

B-57Bs were modified with a low light level television camera plus a forward-looking infrared (FLIR) set and a laser guidance system.

To enable the crew to fire effectively at night, a low light level television (LLLTV) camera, which moved in elevation with the main gun, was fitted to the mantlet.

The F-117 uses passive infrared and low light level television sensor systems to aim its weapons and the F-22 Raptor has an advanced LPI radar which can illuminate enemy aircraft without triggering a radar warning receiver response.

Low light level television, initialized as LLLTV, is a type of electronic sensing device, usually a CCD camera sensitive to wavelengths above the normal "visible" (0.4 to 0.7 micrometre) wavelengths, and into the short-wave Infrared - usually to about 1.0 to 1.1 micrometres.
