Abstract:Free space optical communication (FSOC) represents a promising technology to enable a secure transmission with high data rates over long distances. Ensuring proper operation in turbulent atmospheric conditions by adaptive optics (AO) is essential for the general feasibility of FSOC. A bottle neck of the AO performance is the limited speed of control loops based on Shack-Hartmann wavefront measurements. Alternatively, holographic wavefront sensors provide the potential for an increased measurement speed by enab… Show more
