Cylindrical wavefront
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 … WebA cylindrical wavefront comes from a horizontal slit opening like in diffraction ,etc. A spherical wavefront comes from a point source nearby like a burning candle. Wave fronts are the set of waves which have the …

A wavefront is an imaginary surface representing corresponding points of a wave that vibrate in unison. A wavefront is the set of all locations in a medium where the wave is at the same phase. This could be where all the crests are, where all the troughs are, or any phase in between.
