OPTICAL SENSOR AND METHOD FOR MEASURING PROFILES

摘要

The invention relates to an optical sensor (5) for measuring profiles according to the principle of the light section method, comprising the following: at least one line projector (6) that emits a light line (9) onto an measurement object (8), the profile of which is to be measured; at least one image recording element (7) comprising a sensor element (2) and one lens arrangement (19) for detecting the reflected beam of the measurement object (8), wherein the sensor element (2) is not attached parallel to the plane of the lens arrangement (19), and wherein the sensor element (2) is supported at a plane (A'-B') in such a way that it moves relative to the optical axis (3) of the image recording element (7) such that the depth range of the image recording element (7) can be adjusted. The invention further relates to a measurement arrangement having the optical sensor (5), and a respective method for measuring profiles.
