Verfahren und Vorrichtung zur optischen Abstandsmessung

DE 102005061464 A1 UPAB: 20070817 NOVELTY - Used for measurement from two sources of light with different average wavelengths ( L), light is guided with a probe to a measuring object surface. Reflected light is picked up again and fed to an interferometer with a plane mirror arranged at a slant so as to generate interference bands, which are detected with a line camera. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an optoelectronic measuring device for absolute measurement of gaps/clearances in two or more stages with different large areas of clearness and different measuring accuracy. USE - For absolute opto-electronic measurement of gaps/clearances. In interferometric measurement. ADVANTAGE - The interference bands are detected with a line camera aligned vertically to the interference bands
