摘要

The Georgia Tech Research Institute (GTRI) has developed a turbulence profiling lidar system based on the differential image motion concept. The lidar measures a profile of mean square wave front tilt differences by focusing a laser guide star at multiple ranges and then computing the differential image motion variance of guide star images collected through multiple sub-apertures on the receiver. Direct inversion of the resulting integrals suffers from high noise gain, so several different techniques were investigated to determine the refractive turbulence profile. The best inversion method uses a non-linear fitting algorithm to fit a collection of functions to the differential image motion profile. Each of the fitted functions then maps to a profile of refractive turbulence.
