You'll see that far from the origin, indeed, the wavefront is close to being flat, so you can approximate the wave function with a (fading) sinusoid. But near the origin the wavefront is quite curved, and its curvature becomes infinite at the origin.

WebIn this paper, we present the results of a comparative analysis of the sensitivity of interferograms to wavefront aberrations recorded with flat and cylindrical reference beams. Our results show that compared to classical linear interferograms based on flat wavefronts, cylindrical interferograms have at least 10% higher sensitivity for radially asymmetric … WebCylindrical Wave Front. When the source of light is linear, the wavefronts are cylindrical in shape. All the points are equidistant from the source.
