Abstract

We report recent development in real time control system of Subaru adaptive optics system. The main topic is modification of the real time control system for laser guide star operation. The primary change is appending lower order wave-front sensor. And also, an auxiliary tip-tilt and focus control are appended before higher order waver-front sensor to absorb the perturbation of the laser beam and height of sodium layer. Our implementations using the control gain matrix are introduced thoroughly from the basis of the system design and down to the details. Also, other new function and prospects in the near future will be presented for the cascaded average monitor and the time domain over sampling.
