Abstract
An ultrahigh-sensitivity color high-definition television (HDTV) camera has been developed. It consists of three proximity-focused image intensifier tubes with a large image size (useful area : 40mm diameter) and three frame-interline-transfer charge-coupled devices (CCDs) (2/3-inch, 2million pixels). The images are relayed by high-quality lenses with a reducing power of 1/3.6. The camera' s sensitivity is 3000times that of conventional HDTV CCD cameras. It can caputre iamges of meteors from the ground and of the various hues of celestial bodies when used with an advanced astronomical telescope.
