Abstract
A measuring device for detecting dimensions of bores has a light source emitting a light beam and a beamsplitter for splitting the light beam into a reference beam and a measuring beam. A reference mirror is arranged downstream of the beam splitter. The measuring beam is supplied to a measuring location of the bore and reflected on it. The reference beam is supplied to the reference mirror and reflected on it. The reflected beams are temporally incoherent and are recombined on the beamsplitter to form a recombined beam supplied to a receiver. Reference mirror and receiver have a lateral displacement relative to an optical axis of the measuring device, or the reference mirror is arranged laterally adjacent to the optical axis and the beam splitter at a slant to the optical axis. The measuring device is integrated into a tool or connected to a tool receptacle.
