Wave-front estimation from wave-front slope measurements

摘要: The problem of wave-front estimation from slope measurements has been examined a least-squares curve fitting model point view. It is shown that the measurement sampling geometry influences selection for phase estimation. Successive over-relaxation (SOR) employed to numerically solve exact zonal problem. A new gradient introduced and its error propagator, which relates mean-square noisy measurements, compared with two previously used models. technique rapid extraction aperture functions presented. Error propagation properties modal are evaluated results.
