The system uses a simple quad cell detector for both tracking and imaging, employing an advanced scanner system and reconstruction technique to perform imaging. Image reconstruction and centroid tracking algorithms have been defined and characterized analytically and numerically in terms of accuracy and signal-to-noise performance. A dedicated high-speed digital processor system was developed and used to implement the imaging and tracking algorithms in conjunction with a specially designed optical breadboard of the imager-tracker system.
