Abstract
An apparatus for contactlessly measuring a measurement object is proposed, which has an optical sensor, the optical sensor having an optical probe having a light source and a measurement objective for directing a light beam onto a measurement object and a receiver device for detecting a light beam reflected from the measurement object and generating a corresponding measurement signal; an advancing apparatus for altering the distance between the optical sensor and the measurement object in a first coordinate direction in a manner dependent on the measurement signal generated by the receiver device; and an evaluation unit for determining the coordinates of the measurement point on the measurement object. In order to avoid or at least reduce a so-called contouring error that occurs in conventional measurement apparatuses, the receiver device has a position-sensitive receiver which generates an evaluatable measurement signal within a programmable measurement window; the advancing apparatus sets the distance between the optical sensor and the measurement object in such a way that the receiver of the receiver device receives the light beam reflected from the measurement object within the measurement window; and the evaluation unit determines the coordinates of the measurement point on the measurement object from the position of the optical sensor and the measurement signal generated by the receiver device.
