Abstract

A real time VLSI optical centroid processor has been developed as part of a larger Shack-Hartmann wavefront sensor system for applications in adaptive optics. The implementation of the optical centroid detection system was demonstrated successfully using a hardware emulation system. Subsequently, the design has been implemented as a single-chip solution. This has advantages in terms of power consumption, system size and cost. The design of the different components of the system will be discussed.
