Abstract
A method for determining wavefront shapes of N angular channels CL of different propagation directions PL, said propagation directions PL being 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 Δαij defined by Δαij=arccos, where “·” stands for the inner product between and .
