Paper Abstract

The three-wave lateral shearing interferometer is an interferometer specially designed for optical testing. It determines three non-collinear phase gradients from one single fringe pattern. From these quantities, two orthogonal derivatives and the measurement error are estimated, allowing the reconstruction of the aberrated wavefront. This new interferometer has several benefits; among them that its sensitivity and dynamics can be easily adjusted to the analyzed aberrations.
