Adaptive Compensation for Atmospheric Turbulence Effects on Optical Propagation,
Abstract
Optical wavefronts, propagated in atmospheric turbulence after significant degradation manifested as beam spread, beam wander, and scintillation. We review, very generally, the state of progress of this field of research and discuss recent efforts to overcome the limiting effects of refractive turbulence. Adaptive optical systems are being developed to sense the phase distortion present on propagated beams and to compensate for these aberrations in real time. We present equations describing the magnitude of the turbulence effect and also describing the degree to which compensation may be achieved. Supporting data are presented as well. (Author)
