Paper Abstract

In optics, there are two notable groups of wavefront recovery techniques: the interferometric and geometric ones. Some intensity patterns obtained with these techniques can be quickly related to typical aberrations such as coma or astigmatism. However, the patterns obtained with phase retrieval techniques have not been studied yet. In this work, we proposed and developed a computational tool to obtain intensity distributions in any perpendicular plane of well-known and well-behaved beams, such as parabolic or Gaussian beam wavefronts.
