摘要： Disclosed herein is a method including: (i) providing a light transmissive sample including nominally parallel internal facets, which are about perpendicular to an external surface of the sample; (ii) providing an optical element having a refractive index about equal to that of the sample and including an external first surface and an external second surface acutely inclined relative thereto; (iii) positioning the second surface of the optical element adjacent to the first surface of the sample; (iv) impinging light beams on the first surface of the optical element, about normally thereto; (v) sensing light beams, which exit out of the sample following passage of the impinging light beams via the optical element, transmission thereof into the sample, reflection once off the internal facets, and exit out of the sample; and (vi) based on the sensed data, computing a deviation from parallelism between the internal facets.

摘要： For alignment of rotational shafts, two devices for attachment to circular faces of two shaft segments. Each of the two devices has a laser photoelectric device for ascertaining a dimension of displacement of the two shafts from a desired axis of rotation relative to each other. Each of the two devices having a base surface with two linear contact edges designed to engage with a circumferential surface of a shaft and to ensure alignment between the device and an axis of rotation of the shaft to within a tolerance compatible with alignment tolerances of the shaft. Each of the two linear contact edges includes at least two terminal end regions and a center region together defining a line contact at linear intersection of two surfaces meeting at a non-zero angle linear contact edges designed to affix and release from the shaft surface, and to ensure parallel alignment between the device and an axis of rotation of the shaft to a precision allowing measurements to within tolerances required by machinery driven by the shaft. The base surface of at least one of the devices has been modified from its commercially-delivered condition to provide raised rails designed to improve tactile feedback of to a user of the alignment between the base and an axis of rotation of the shaft, and has affixed thereto two rails designed to improve tactile feedback of to a user of the alignment between the base and an axis of rotation of the shaft. Each base has a magnet and a switch to vary magnetic flux for affixation and release from the shaft surface. Each device has brackets designed to securely and reproducibly position laser photoelectric devices relative to the base and axis of rotation of the shaft. The attaching includes a human placing at least one of the devices slightly askew relative to the axis of rotation of the shaft, and the human gently twisting the device to allow the liner contact edges to seat on the circumferential surface of the shaft, to provide tactile feedback to the human to confirm parallel alignment between the at least one device's laser photoelectronic device and the axis of rotation of the shaft.

摘要： Aspects of the present disclosure describe estimating/measuring core-cladding concentricity error in optical fibers. In sharp contrast to the prior art, our inventive method is based on measuring a seemingly unrelated property of fibers called guided acoustic wave Brillouin scattering (GAWBS). As we shall show and describe, by analyzing this GAWBS property we advantageously determine what level of CCCE is exhibited by the optical fiber.

摘要： A metrology system may include an imaging sub-system including one or more lenses and a detector to image a sample, where the sample includes metrology target elements on two or more sample layers. The metrology system may further include a controller to determine layer-specific imaging configurations of the imaging sub-system to image the metrology target elements on the two or more sample layers within a selected image quality tolerance, where each layer-specific imaging configuration includes a selected configuration of one or more components of the imaging sub-system. The controller may further receive, from the imaging sub-system, one or more images of the metrology target elements on the two or more sample layers generated using the layer-specific imaging configurations. The controller may further provide a metrology measurement based on the one or more images of the metrology target elements on the two or more sample layers.

摘要： A maintenance tool and alignment system are provided having a first optical device and a second optical device. The tool includes the at least two optical devices such that they do not occupy the same space or interfere with the tool's function. In some embodiments, the first and second optical devices define or project a first viewing plane and a second viewing plane. The first viewing plane and second viewing plane are transverse to one another and intersect within a field of view of the first optical device creating an intersection. The intersection of the first and second viewing planes allows for the tool, via a processor or a control device, to alignment the tool within a workspace without a dependence on an estimation of a distance of the tool relative to the workspace.

摘要： A method for measuring and registering 3D coordinates has a 3D scanner measure a first collection of 3D coordinates of points from a first registration position. A 2D scanner collects horizontal 2D scan sets as 3D measuring device moves from first to second registration positions. A processor determines first and second translation values and a first rotation value based on collected 2D scan sets. 3D scanner measures a second collection of 3D coordinates of points from second registration position. Processor adjusts second collection of points relative to first collection of points based at least in part on first and second translation values and first rotation value. Processor identifies a correspondence among registration targets in first and second collection of 3D coordinates, and uses this correspondence to further adjust the relative position and orientation of first and second collection of 3D coordinates.

摘要： An assembly includes a base member having a fiducial marker, a vehicle component having a housing mounted to the base member, and an image sensor fixed to the housing and aimed at the fiducial marker. A method includes mounting the vehicle component to the base member of a vehicle, capturing a baseline image of the fiducial marker, capturing a subsequent image of the fiducial marker, comparing the subsequent image to the baseline image, and adjusting operation of the vehicle component in response to the identification of differences between the baseline image and the subsequent image.
