Abstract

We describe an adaptive optical closed loop system with bimorph mirror as a wavefront corrector and CCD camera at the focal plane of the lens as a sensor to obtain a good focal spot. Adaptive system can correct for the low-order aberrations with the frequency of corrected aberrations about 5 Hz. These parameters are mostly determined by the deformable mirror properties and multi-dither algorithm.
