Patent ID: 7092102

Claim:
A measuring device for detecting dimensions of test samples in the form of hollow bodies having a recess, the measuring device comprising: at least one light source emitting a light beam; a beamsplitter arranged downstream of the light source and configured to split the light beam into a reference beam and a measuring beam; a reference mirror arranged downstream of the beam splitter, wherein the measuring beam forming a measuring arm is supplied to a measuring location of a test sample and is reflected on the measuring location as a first reflected beam and the reference beam forming a reference arm is supplied to the reference mirror and is reflected on the reference mirror as a second reflected beam; wherein the first and second reflected beams are temporally incoherent and are recombined on the beamsplitter to form a recombined beam; a receiver arranged such that the recombined beam impinges on the receiver; wherein the reference mirror and the receiver are laterally displaced away from an optical axis of the measuring device at lateral spacing relative to the optical axis; wherein the measuring device is configured to be integrated into a tool or to be connected to a tool receptacle.
