Correction of atmospheric effects on the propagation of laser light can be achieved with adaptive optics (AO) by relying on adequate wavefront sensors. For free-space laser communications and for tracking of high-speed airborne objects Shack-Hartmann sensor is not effective. Its performance is severely limited by scintillation. We characterize a promising modal alternative: digital holographic wavefront sensor (DHWS). We examine the performance of the sensor for single-, and multimode operation and its dependence on the detector size, scintillation, residual tip/tilt and misalignments.
