Abstract
A method for determining wavefront shapes of N angular channels Cof different propagation directions P, said propagation directions Pbeing determined by a mean propagation direction vector, from a single signal image acquisition I(x,y) of a multi-angular signal light beam containing said angular channels, each angular channel Ci being separated from other angular channels Cj by an angular separation Δαdefined by Δα=arccos, where '·' stands for the inner product betweenand.
