Optical tracking using charge-coupled devicesThe extraction of precise positional information from CCD images of point-source and extended optical targets is considered, and three examples of CCD optical trackers for space-based operation are described. For ideal point sources, a centerfinding accuracy of 1/100 pixel and a measuremet jitter of less than 1/250 pixel have been obtained using thinned, backside-illuminated devices. Tracker accuracy is shown to be limited by small variation in the optical image shape. Techniques for tracking, and methods for searching the entire field for the desired targets, are also discussed.
