  • Patent number: 11959738
    Abstract: An apparatus and method for inspecting an object by optical triangulation, where the signal of interest in a captured image corresponds to an interaction between a light beam and an environment surrounding the object rather than between a light beam and the object itself. The surrounding environment may be configured to interact in a manner that is detectable by filling it with a flowable scattering medium, e.g. a gas, mist or vapour comprising a suspension of fine particles in air. Light that is scattered by the flowable scattering medium is visible in a captured image. Where the flowable scattering medium is not present, e.g. because the object blocks it, the scattered signal is less. A boundary of a scattered signal region may thus provide information about the location of an object.

  • Patent number: 9013716
    Abstract: The invention provides a positioning device for locating a planar light beam emitted by an optical triangulation sensor across a diameter of a hole formed in a surface of an object. The positioning device has an adjustable guiding element which is capable of locating an optical triangulation sensor at the same distance away from holes have a range of diameters. The guiding element is movably mounted relative to a platform that is fixed to the optical triangulation sensor. The guiding element comprises a body which is insertable into the hole, the body having a pair of contact surfaces for contacting diametrically opposed portions of the hole, the pair of contact surfaces being opposed to each other in a direction orthogonal to the plane of the planar light beam.

  • Patent number: 8274662
    Abstract: An optical, such as a laser, triangulation sensor is disclosed in which a configuration of an output light beam is controlled using a mask in front of a light source. The configuration may include a plurality of coplanar spatially separated planar light beams. The mask may be movable to provide different light beam configurations. Masking parts of the light beam enables unwanted features on the measurement surface to be omitted. Also disclosed is a guide element for an optical sensor for facilitating hole diameter measurement. The guide element has contact surfaces lying on a virtual conical surface which abut the hole edge to enable consistent placement of the light beam with respect to the hole centre. Also disclosed is a guide element for an optical sensor having an aperture for framing surface features, such as a rivert to permit accurate location of the light beam therewith.
