  • Patent number: 7525666
    Abstract: An interferometric measuring device, especially for measuring the shape of a surface of an object, includes a radiation source emits a short coherent electromagnetic radiation, a component, in particular a beam splitter, to form an object beam that is guided to the object via an object light path, and a reference beam guided to a reference plane via a reference light path, and a pickup element, by the use of which an electromagnetic radiation, that is reflected by the object and the reference plane and brought to interference, is able to be picked up. In this context, an adaptive optical element is provided, with the aid of which the imaging of the object on the pickup element and/or the wave front of the reference beam and/or the optical path length in the reference light path and/or in the object light path may be influenced.

  • Patent number: 7456974
    Abstract: An optical measuring system for detecting geometric data of surfaces of at least one object is described, comprising a beam delivery section, a probe system which is connected to the latter and has a plurality of probe outputs for output of a particular measuring beam to an assigned particular surface location and recording the light reflected back by the surface, and having a downstream analyzer unit for determining the geometric data on the basis of light reflected back by the surface locations. A very accurate and mechanically robust determination of surface geometric data, e.g.

  • Publication number: 20050052656
    Abstract: An interferometric measuring device for recording geometric data for surfaces of at least one object, including a beam supply section including a modulation interferometer fed by a light source including temporarily coherent broadband radiation, a measuring interferometer system that is connected thereto and includes a plurality of probe units for emitting radiation of measuring beams onto the assigned surface locations and recording the radiation reflected by the surface locations, the radiation forming interference with radiation reflected by a related reference element system, and including a downstream receiving and evaluation device for determining geometric data on the basis of the interfering radiation.
