Abstract

The crosstalk problem inherent in holography based modal wavefront sensing (HMWS) becomes more severe with increasing aberrations of the incident beam. In this paper, the cause of crosstalk is theoretically revealed and then demonstrated using simulations. For extending the use of HMWS in correcting atmospheric turbulence introduced aberration, the sensor response is statistically analyzed with random aberrations created in accordance with the atmosphere turbulence model. The system parameters are optimized considering the turbulence strength and calibrated response curves are further used to improve the sensor performance. The simulation and first preliminary experimental results are shown for validating the method.
