Computer generated holograms for testing optical elements.
The application of computer generated holograms to the interferometric testing of aspheric optical elements has been investigated, and it has been shown that they provide a convenient and practical method of producing an aspheric reference wavefront.
متن کاملOptical alignment with computer generated holograms
Computer generated holograms (CGHs) have been successfully used for wavefront correction for measuring aspheric surfaces. Features on the CGHs have assisted the alignment of the optical test equipment. CGHs can also be used to provide alignment references for other complex optical systems. This paper discusses the types of CGHs that can be used for optical alignment and gives some examples.
متن کاملNonlinear computer-generated holograms.
We propose a novel technique for arbitrary wavefront shaping in quadratic nonlinear crystals by introducing the concept of computer-generated holograms (CGHs) into the nonlinear optical regime. We demonstrate the method experimentally showing a conversion of a fundamental Gaussian beam pump light into the first three Hermite-Gaussian beams at the second harmonic in a stoichiometric lithium tant...
متن کاملGeneration of optical phase singularities by computer-generated holograms.
There has recently been considerable interest in optical fields that exhibit phase singularities, which manifest themselves as isolated dark spots in the modal patterns of certain lasers. Each dark spot has a topological charge that represents the number of 2vr accumulated when the phase gradient is integrated around it. The wave fronts near a singularity have a helical structure, while the fie...
متن کاملNonuniformly sampled computer-generated holograms
Ravikanth Pappu Massachusetts Institute of Technology Media Laboratory Spatial Imaging Group 20 Ames Street Cambridge, Massachusetts 02139 E-mail: [email protected] Abstract. An novel algorithm for computing holographic fringe patterns based on nonuniform sampling is described. We show both analytically and via simulation that nonuniform sampling reduces the number of samples required to repr...
