Abstract

The OPTECAL testbed has been fabricated for the purposes of developing and evaluating control algorithms for active, closed loop control of optical systems. The testbed has the capacity for controlling up to 84 degrees of freedom, including deformable mirrors and segmented mirrors. Evaluation of optical performance is provided by either a phase measuring interferometer, shearing interferometer or image based sensor (IBS). The modular design of the operational software allows for easy implementation of new control algorithms. An accurate software simulation of the optical prescription is also incorporated to facilitate initial algorithm develoment. One imagebased algorithm and one wavefront based algorithm have been successfuly evaluated. Future plans include the investigation of other optical control algorithms, such as phase retrieval techniques and extended scene measurements.
