Wavefront sensing using correlations of two speckle intensity measurements and a Shack Hartmann-based algorithm
Abstract
A wavefront reconstruction technique using correlations of two axially-displaced speckle intensity measurements in the Shack Hartmann configuration is presented. Phase maps are reconstructed from simulated speckle patterns. Recording of only two speckle patterns allows the applications of the technique in dynamic wavefront sensing.
