Abstract
Two methods are presented for the amplitude and phase recovery of optical beams with rotational symmetry. Thes are the tomographic method based on the ambiguity function and the one-step wavefront recovery based on the measurement of a phase-space distribution closely related to the Wigner distribution function. The results obtained from thes two methods are compared, and the appropriateness of using either one of them for specific situations is discussed.
