Method for detecting the distances from objects using a triangulation sensor and triangulation sensor for performing the method

摘要

The light reflected from an object, irradiated by a phototransmitter, is picked-up by a detector and evaluated to a spacing signal. Typically the reflected light is picked-up by several detectors adjusted to different detecting widths. The detector signals are so linked that approximate linear course of the spacing signal is obtained over the entire detecting width. Pref. the light is transmitted by several phototransmitters with different scanning values. Independent claims are included for a triangulation sensor.
