ABSTRACT:
The invention relates to a device for the three-dimensional determination of the movement between two bodies, in which the components of movement are determined by means of two measurement-value transmitters, each of which has a first transmitter element and a second transmitter element which are movable relative to each other. One transmitter element has, in this connection, at least one light path or measurement path within which a filter acting as dispersion screen is movable on the other transmitter element.
