Paper Abstract

The THX 7887A sensor developed by Thomson-CSF Semiconductors Specifiques is a high resolution frame transfer CCD designed for medical applications (digital X-ray imaging: fluoroscopy and angiography for instance), for industrial (machine vision, pattern recognition or process control, ...) and scientific applications (e.g., optical correlation...). The design of the array is discussed: it consists in 1024 X 1024 photosensitive pixels of 14 micrometers X 14 micrometers . It features on-chip memory and four parallel outputs running at 20 MHz maximum data rate each, thus compatible with frame rates as high as 60 Hz (one frame is made of 1024 X 1024 true pixels without any interlacing). Other specific on-chip capabilities are available: binning 2 X 2 pixels (leading to 512 X 512 or 512 X 1024 format), anti-blooming and exposure time control. Design has been optimized so as to minimize high speed clock number and to facilitate driving of the chip. Main attractive performances measured are low noise and dynamic range higher than 12 bits at 60 frames per second, together with low dark signal, high responsivity and very low optical/electrical crosstalks.
