English abstract:
Wavefront sensing is important in many optical
measurement systems and adaptive optics. The speed of the
wavefront sensor determines the achievable temporal resolution
of dynamic measurements and the bandwidth of adaptive optics
systems. In this paper we propose a versatile high-speed Shack-
Hartmann wavefront sensor based on an industrial smart camera.
The sensor uses a parallel processing scheme for high-speed
measurement of wavefront deformations and offers runtime
reconfiguration. An FPGA based centroid detection is presented,
adding an overall time delay of only 380ns. The wavefront
estimation is demonstrated on an external PC using zonal and
modal reconstruction.
