With the delivery of WIRCam, ASIAA continues its instrumentation collaboration with CFHT on the development of CCD curvature wavefront sensor “FlyEyes”. The main goal of this project is to evaluate and characterize the MIT CCID-35 detector as a suitable replacement for the avalanche photo diode modules (APDs) in the existent curvature wavefront sensor. ASIAA mainly contributed to the hardware interface definition, detector controller system software design, CCD characterization, and AO system simulation.
