An optical triangulation sensor and method for testing of an optical triangulation sensor

摘要

An optical triangulation sensor for the detection of objects according to the principle of the downstream of the basis of evaluation, in particular for use in the security area,with a radiation source (10) for the transmission of light (12),with an optical transmitter device (14) for directing of the light (12) on one object (20) and a background (30),with a near the symbols (60) for the detection of of the object (20), reflected light (22),with a remote receiver (50) for the detection of of the background (30), reflected light (32) andwith a detector optic (40) for directing of the object (20) reflected light (22) is close to the receivers (60) and to direct the of the background (30) reflected light (32) on the remote receiver (50),characterized by the,that for testing of the nahempfängers (60) a test source (80) for the transmission of test light (82) is present,that the test source (80) is arranged so that the test light (82) both on the near the symbols (60) as well as on..
