Abstract

Two tracking sensor breadbroads have been developed for the European SILEX program. Critical requirements to be met by these sensors include the determination of the 1-sigma position of the focused laser spot on the detector surface to accuracies of less than 100 nm, with update frequencies as high as 8 kHz, and the minimum optical power level of 110 pW. The design is based on the use of a 14 x 14 pixel CCD array, where the spot position is determined to small subpixel accuracies over the central 2 x 2 pixel area via a centroiding algorithm executed in a microprocessor. Coarse position measurements are also made over the full area at rates up to 2 kHz.
