More Information
Summary:A device for carrying out holographic interferometry has a laser, in each case one beam preparation device for at least one laser beam and one illuminating beam, and a hologram storage disc. With regard to ease of handling for reliable industrial use, the laser and the holographic beam preparation devices are arranged in a common station, laser beam transport out of the station being provided for the illuminating beam and each reference beam via optical waveguides to at least one mobile holography measuring head (sensing head, sensor). In a preferred embodiment, the holography measuring head has a video camera for recording holograms in the region of the hologram storage disc, the video camera being connected for on-line evaluation to a separate evaluation station via an electrical line.
