Abstract: A measuring system for triangulation-based distance measuring device having a light emitting unit, a light receiving unit for detecting measuring light reflected from an object and a processing unit for deriving distance information based on a detected reflection of measuring light. The system comprises a visual guiding unit projecting a visual marker onto the object. The light emitting unit and the visual guiding unit provide a light reflection onto the object by emitting the measuring light and the projection of the visual marker onto the object. The measuring system comprises a camera, the field of view of the camera being greater than the field of view of the light receiving unit and the camera captures an image covering the light reflection and the projection of the visual marker and to provide image information according to a captured image.

Abstract: A method for controlling a distance between a non-contact measurement probe head of a CMM and a work piece during a measurement. The method comprises providing steering commands to steer the work piece and/or the probe head through a measuring path comprising measuring positions, performing at a measuring position a measuring step comprising providing distance adjustment steering commands to set the distance between the probe head and the work piece, projecting a primary measuring beam pattern onto the work piece, acquiring a secondary measuring beam pattern originating from an interaction of the primary measuring beam with the work piece, deriving surface information based on the secondary measuring beam pattern, deriving information regarding the distance between the probe head and the work piece, deriving a distance deviation based on a distance target the derived distance information, providing the distance deviation for a distance adjustment performed at a subsequent measuring position.

Abstract: Optical sensors are adapted for distance measurement by emission and capture of measuring radiation reflected from an object to be measured. The optical sensors can be used with measuring devices, including coordinate measuring machines. The optical sensors have an optomechanical coupling unit, configured for automated coupling of the optical sensor to the measuring device and for bidirectional measuring radiation transmission between measuring device and optical sensor. The optical sensors have a first optical measuring channel, by which bidirectional measuring radiation transmission is provided between the measuring device and a first exit window of the optical sensor.
