Paper Abstract

Several wavefront sensing techniques were tested against a common aberrated beam. The error on the beam was predominantly spherical aberration. The techniques included Shack- Hartmann Test, Lateral Shear interferometry, Point Diffraction Interferometry, and a Knife Edge Test. Beam calibration was accomplished using Fizeau Interferometry.
