17 October 1997 Simplified user interface for CFHT's adaptive optics system

Complex instruments generally have complex control requirements. However theoretical analysis, instrument design, and software planning can allow a simple user interface to control the instrument successfully. A case in point is the Canada-France- Hawaii Telescope Adaptive Optics system. In normal operation one button push is sufficient to begin adaptive correction. During system design much effort was placed in automatic gain optimization for bimorph mirror control. This has allowed the system to run unattended for hours at a time. During software design and development other control points were identified and decision paths formulated to allow their parameters to be adjusted automatically. So, although a complete engineering interface was designed and implemented, in practice it has only been used for initial development and acceptance testing. Normal observing needs only a simple form for the astronomer. We present the resulting interface and trace some of the design decisions that allowed us to simplify this potentially complex interface.
