Real-time wavefront measurement based on GPU-accelerated parallel algorithm using phase diversity images

In this study, we introduce a novel real-time measurement and correction method for time-varying wavefront aberrations. Central to this method is a GPU-accelerated parallel algorithm based on phase diversity images. We apply an approximate model for the point spread function to reduce the computatio...
