Non-contact triangulation probe system

摘要

A non-contact triangulation probe system including a base plate; a first non-contact triangulation probe including a light source mounted on a first movable slide, the first slide being disposed on the base plate and arranged for sliding motion therealong, a source of movement for the first slide being associated therewith; a first position sensor for determining the relative position of the first probe and providing an output signal corresponding thereto; a second non-contact triangulation probe including a light source mounted on a second movable slide, the second slide being disposed on the base plate and arranged for sliding motion in the same direction as the first slide, a source of movement for the second slide being associated therewith; a second position sensor for determining the relative position of the second probe and providing an output signal corresponding thereto; the first and second probes being arranged to face each other such that the light beams emitted by the probes coincide on the same optical axis; a microcomputer arranged to actuate the source of movement for the first and second slides, to receive the output signals from the first and second position sensors, and to receive output signals from the first and second probes.
