High quality electronic imaging systems are highly demanding in more and more resolutions. For Earth observation applications through space-borne imaging pushbroom systems, high pixel count focal planes are required. They are commonly obtained thanks to butting several CCD linear image sensors, mechanically in one focal plane, or through optical linear beam splitters. These solutions involve high precision positioning and thermal stability to insure perfect imaging line reconstruction. Optical beam splitting avoids blind space between elementary devices, and thus is preferred. However it leads to a heavy and large camera. The new linear image sensor developed by Thomson-CSF is made of 12,000 pixels. This monolithic CCD allows us to cover the whole field of view of a camera in the SPOT 5 mission, and drastically simplifies the whole space-borne instrument. It features on-chip anti- blooming function on each 6.5 micrometer by 6.5 micrometer square pixel, and is mounted in a dual in line ceramic package, specially designed for high flatness and mechanical stability. Main characteristics of this new high resolution CCD linear image sensor are high output data rate up to 40 MHz, 80 dB large dynamic range, very low lag, as well as high electro-optical performances in photo-response uniformity, low dark current and noise. The paper details the CCD architecture, and reports on electro-optic, geometrical and mechanical performances.
