Design of controlling software for force actuator group of thin-mirror active optics

A software was designed for controlling experiments of an force actuator group, which was intended to be used in thin-mirror active optics. In the beginning, requirements of the controlling experiments on the software were analyzed, from both function angle and performance angle. Also, five working modes, such as correcting mode, testing mode, installing mode, stopping mode and restoring mode, were designed for the software according to practical requirements, and transition conditions between different working modes were discussed. Afterwards, the software was divided into three modules, such as data-transmission module, data-procession module and user-interface module, and design of each module was explained. Finally, the software was tested with each working mode, and a correcting experiment with an aluminum mirror was conducted in the correcting mode. Results of the test and the correcting experiment show that this software can meet almost all the anticipative requirements of the force actuator group experiments.
