Abstract: An optical measuring apparatus for comprising, in combination, a polarization type interferometer including a polarization type beam splitter in which a polarized beam of light is split into orthogonally polarized reference and test beams, an array of detectors arranged in a line for creating a plurality of phase shifting interferograms, and a scanning device for moving the object in a direction perpendicular to a long axis of the detectors.

Abstract: A source module (12) generates mutually orthogonally polarized beams of light as emanating from two spatially separated point sources (Sv, Sw) for use in a phase shifting interferometer.

Abstract: A back-end assembly for use with a front-end assembly in acquiring phase-shifted interferograms having a plurality of imaging modules (Ma, Mb, Mc). Each module (Ma, Mb, Mc) has a quarter wave plate (30a, 30b, 30c), a polarizer (32a, 32b, 32c), and an image sensor (34a, 34b, 34c) so that each polarizer has a different rotation orientation thus acquiring phase-shifted interferograms.

Abstract: There are provided fiber optic local convergence points (“LCPs”) adapted for use with multiple dwelling units (“MDUs”) that facilitate relatively easy installation and/or optical connectivity to a relatively large number of subscribers. The LCP includes a housing mounted to a surface, such as a wall, and a cable assembly with a connector end to be optically connected to a distribution cable and a splitter end to be located within the housing. The splitter end includes at least one splitter and a plurality of subscriber receptacles to which subscriber cables may be optically connected. The splitter end of the cable assembly of the LCP may also include a splice tray assembly and/or a fiber optic routing guide. Furthermore, a fiber distribution terminal (“FDT”) may be provided along the subscriber cable to facilitate installation of the fiber optic network within the MDU.
