Claim 19:
20. The wavefront sensor according to claim 19, wherein the computing means are further configured to estimate a minimum TLI(Ai) and a minimum WLI(Ai), and a minimum of the difference DAi which is obtained by computing for each zero-mean cross-correlation product image of zero-mean cross-correlation product images for each respective portion of the macropixel of surface (Ai), between a signal sub-image I(x,y) and each of the reference intensity patterns RL(x, y) with respective (x, y) coordinates fir each respective portion of the macropixel of surface area (Ai), wherein the zero-mean cross-correlation product images between the signal sub-image I(x, y) and each of the reference intensity patterns RL(x, y) having a peak, wherein the intensity-weight data WLI(Ai) is the amplitude of the peak and the deformation data TLI(Ai) is a displacement vector between said peak or its centroid from center of each respective zero-mean cross-correlation product image of the zero-mean cross-correlation product images.
