Machine part e.g. shaft, three-dimensional location`s qualitative or quantitative determination device for e.g. measurement robot, has optoelectronic sensor determining incidence points of light beam flared in two planes

摘要

The device has a transmitting device emitting multiple light beams e.g. laser beams (40, 50) with a crosshair-shaped or star-shaped cross section, which is flared in two planes. A receiving device has two linear optoelectronic sensors e.g. position sensitive sensors (42, 52) determining incidence points of the light beam flared in the two planes on the indicated optoelectronic linear sensors. The lengthwise axes of the optoelectronic linear sensors are aligned at an angle of about 40-120 degrees relative to one another. An independent claim is also included for a process for qualitative or quantitative determination of a three-dimensional location of two bodies relative to one another.
