Abstract: The invention relates to a position detection system for the contactless interferometric detection of the location of a target object. A target object unit comprises a reference light transmitter, which is configured such that it transmits a reference light beam having curved light wave fronts. The target object unit comprises at least one detector array having a plurality of detector pixels, which is fixed to the target object unit such that the reference light beam of the reference light transmitter impinges on the same.
Abstract: A scanning sensor system for noncontact optical scanning of object surfaces having a sensor head (2) and an optics unit (3) as system components matched to one another. The optics unit (3) can be attached and positioned with high precision on the sensor head (2) by means of a fixing device (4).
