Atmospheric Propagation and Correction of Laser Beams for Communication and Sensing Applications

Correction of atmospheric effects on the propagation of light can be done by adaptive optics (AO). Nevertheless, challenging scenarios like strong turbulence near the ground lead to high failure rates of the traditional AO systems. Unconventional wavefront sensors and AO strategies are developed at Fraunhofer IOSB to provide alternatives for measuring the wavefront deformation of a laser beam.
