    • A Toolbox for Isophase-Curvature Guided Computation of Metrology Holograms

    Metadata Updated: July 29, 2022

    An open-source numerical toolbox , written in the Octave language, for the creation of computer-generated binary and multi-level holograms used in interferometric form error measurements of complex aspheric and free-form precision surfaces and optical wavefronts. In a typical measurement setup for this type of surface, a hologram is used to generate a test wavefront that has the design shape of the surface, which is then compared to a fabricated part using an imaging laser interferometer.
