Abstract

We present an adaptive optical system to stabilize the position of a laser beam passed through the turbulent atmosphere. The system uses two tip-tilt mirrors and is controlled by an FPGA to increase the bandwidth. An internal FPGA structure is presented. FPGA reads the error signal from the sensors formed by quadrant photodiodes and calculates the voltages to be applied to the piezo-driven tip-tilt mirrors by the control units.
