Mosaic CCD focal plane technology for electro-optical space surveillance
Abstract
Design and performance parameters for solid-state CCD visible band imagers being developed as replacements for television-based sensors used in the ground-based electrooptical deep space surveillance system (GEODSS) are described. Fiber optic tailored bundles are employed to increase the apparent size of the CCDs to synthesize minimum 48 micron pixels. Distortions of no more than 1 percent have been achieved by pulling heated bundles during tailoring. Multiple CCDs and bundles serve to upgrade the otherwise 0.56 transmission level of the bundles. Arrays generating 420 x 420 and 840 x 840 pixels are being tested. The read rate is 1 MHz/CCD for one test device, requiring under 0.25 sec to scan the array. The fast scan eliminates image blur and frame subtraction erases star images.
