  • Title: Application of a Shack cube as a beam splitter in interferometers with a local reference beam.
    Author: Shen W, Chang MW, Wan DS.
    Journal: Appl Opt; 1996 Dec 01; 35(34):6648-54. PubMed ID: 21151243.
    Abstract:
    A different setup of the Mach-Zehnder interferometer for testing the convergent wave front is described. A Shack cube is used to replace a traditional recollimator and a parallel-plate beam splitter. An equivalent pupil model has been suggested that describes the point diffraction mechanism. The calibration procedures for the Mach-Zehnder interferometer are described. The Shack-cube beam splitter has the advantages of compactness and better reference-beam quality compared with the recollimator and the parallel-plate beam splitter.
