Paper Abstract
An adaptive optics system running at 1500 Hz was integrated using commercially available components. The deformable mirror was made by Alpao and has 277 actuators on a 1:5mm pitch. The wavefront sensor is based on the OCAM2 EMCCD (Electron-multiplying charge-coupled device) camera from First Light Imaging and a 20×20 lenslet array. We present an initial system integration phase using the Alpao Core Engine toolbox running in a Matlab® environment. During the second integration phase, benchmark tests for Alpao's real-time controller ACEfast show the possibility to obtain a pure delay of τ = 130 µs in a parallel worker configuration with a computing power of 2 CPU/8 core + 4GPU for a problem size equivalent to state-of-the-art adaptive optics systems.
