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.

Abstract: Multi-coordinate measuring and testing machine which is essentially constituted from a fundamental machine unit, a scanning or sensing system which is movable in at least two coordinate directions, and a machine-controlling unit. The scanning or sensing system is constructed as a multi-sensor system and is constituted from a mechanical sensing head or probe with at least one stylus and/or a video scanner and/or a laser scanner which are controlled from a microprocessor and operate independently of each other, and which are selectively either individually actuatable by means of software connected thereto, or can be coupled to each other in a dual or triple combination.
