The UnISIS project uses a laser guide star adaptive optics system with the
Mt. Wilson 100 inch Hooker telescope. This system uses the Adoptics®
software and several custom interfaces designed and built by Riptide Realtime. Communication with these custom interfaces is integrated in
Adoptics. The system underwent a transition from an OS/2 ISA
bus version with 8 DSP processors to a faster real time Linux PCI bus version
with new hardware interfaces. Software which once required 8 DSP processors for
speed was re-written to run even faster under real time Linux, using
only the host computer's 1GHz Intel Pentium processor. In the UnISIS system, the
reconstructor loop in the real time Linux version of Adoptics runs at 333
Hz, reading a 26 x 26 element wavefront sensor and writing to a 177 element
deformable mirror (DM).
Interfaces built by Riptide:
- C40 DSPs to Xinetics DM driver
electronics
- Pentium PC to Xinetics DM driver electronics
- Fiber optic UV camera (Astronomical
Research Cameras) to
de-multiplexed parallel data and real-time hardware capture
