An Intensified CDD (ICCD) camera is an electronic camera, equipped with an intensified CCD as image sensor. The sensor uses an image intensifier that is fiber-optically coupled to the CCD chip to increase the sensitivity down to single photon level.
An intensified CCD camera allows image acquisition at very low light levels over a wide light spectrum and at relatively high speeds. Single photons can be detected and discriminated from CCD noise. Ultra high-speed phenomena can be captured by using the image intensifier as a fast shutter (gating).
