For free-space laser communications and for tracking of high-speed airborne objects Shack-Hartmann sensor is not effective. Its performance is limited by scintillation. We characterize a promising modal alternative: digital holographic wavefront sensor. The sensor is very robust to scintillation, residual tip/tilt and misalignments.
