Paper Abstract

A 256-channel Digital Wavefront Reconstructor System (DRS) has been developed for the Sacramento Peak Adaptive Optics System. The system may be configured with 16 to 256 channels in a single VME chassis. Several thousand channels can be accommodated by adding more VME chassis. The system architecture supports both parallel and serial processing combinations. This flexibility allows it to be adapted to various wavefront sensors or used in other applications that require high-speed parallel data processing in real time. Algorithms may be implemented that perform matrix multiplication, FIR and IIR filters, gain and offset corrections, table lookups, and polynomial evaluations. The use of the DRS in the Sac Peak Adaptive Optics System is presented, followed by a detailed description of the DRS hardware design.
