Paper Abstract

In this paper, high frame-rate Shack Hartmann wavefront sensor with a C-MOS image sensor is presented. To realize high data rate wavefront sensor we adopted the flexible read out technique on C-MOS sensor, which makes it possible to reduce not only the amount of Hartmann spot but also image size. In the preliminary experiments, we have successfully obtained 10x10-Hartmann diagram with a rate of 4 kHz, leading to a high frame-rate wavefront sensor.
