Paper Abstract

We report recent development in real-time control system of 188-element Laser Guide Star Adaptive Optics for Subaru Telescope (Subaru LGSAO-188). The current status is reported, and plans for improvements to enhance the performance are reported as well. A major item is to invoke the optimum gain control, which is being implemented on the data handling system and to be attached to the real time control system. We also explain about other new features on the control system including general response acquisition system as an expansion of response matrix acquisition system.
