Abstract
The three-wave lateral shearing interferometer is an interferometer specially designed for optical testing. It determines three noncollinear 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 wave front. This new interferometer has several benefits; among them is that its sensitivity and dynamics can be easily adjusted to the analyzed aberrations.
