7 February 2003 Tracker development for the starfire optical range 3.5-m telescope adaptive optics system

A new tracker is under development at the Starfire Optical Range (SOR). The tracker system's tilt sensor is based on an optical pyramid that creates a quad-cell effect into avalanche photo diodes, sampled at 5000 frames per second. A suite of hardware and software that allows unprecedented flexibility in control system design and implementation delivers the mirror control signals. The control problems associated with this tracking system are interesting due to lightly damped mirror resonances; these dynamics are handled via a tight inner cage loop. Thus, the controller makes use of both optical feedback and mirror position feedback. This paper discusses the design and implementation of the entire tracker system, including sensor characteristics, steering mirror characteristics, electronics, and control algorithms implemented. Experimental results are presented.
