Abstract: A method of putting a feature of interest on an object and an optical inspection system of a non-contact probe mounted on a positioning apparatus in a desired relationship. The method includes: a) identifying a target point of interest on the object to be inspected by arranging the non-contact probe and object at a first relative configuration at which a marker feature, projected by the non-contact probe along a projector axis that is not coaxial with the optical inspection system's optical axis, identifies the target point of interest; and b) subsequently moving the non-contact probe and/or object so as to put them at a second relative configuration at which the target point of interest and optical inspection system are at the desired relationship, in which the positioning apparatus is configured to guide such motion in accordance with the control path.

Abstract: An optical distance measurement or ranging apparatus, the apparatus including at least one optical pulse generator for generating a train of gating pulses and a train of probe pulses, the train of gating pulses having a different repetition rate than the train of probe pulses. The gating and probe pulses may be ultrashort laser pulses generated by different free-running, mode-locked lasers. An optical probing arrangement for directing the train of probe pulses to one or more objects and for collecting returned probe pulses returned from the one or more objects. The objects may include a target object and a reference object. The apparatus includes a multi-photon effect detector and is configured to direct both the train of gating pulses and the returned probe pulses to the multi-photon effect detector. The apparatus may be used for industrial inspection, machine calibration, position measurement or the like.

Abstract: A method and system for forming a holographic structure in a material. The holographic structure is configured to project a selected target image in the far field under illumination of the holographic structure by a laser. The method calculates a modified design for the holographic structure that encodes a unique identifier within the holographic structure for projecting the target image. The method modifies the material by mapping features corresponding to the modified design into the material so as to form the holographic structure. A basic check of the authenticity of the material is performed by checking whether a projected replica of the target image is as expected. A more detailed check of the authenticity of the material is performed by directly inspecting the features in the holographic structure.
