  • Patent number: 9204129
    Abstract: A non-contact sensing system is provided for acquiring three-dimensional contour information of an object. The system is comprised of: a light source subsystem operable to scan a point of light in an area of illumination; a first imaging device having a field of view arranged to intersect with the illumination area and operable to capture image data; and a second imaging device having a field of view arranged to intersect with the illumination area and operable to capture image data. A first control module is in data communication with the first imaging device to determine contour information for an object in the field of view of the first imaging device and report the contour information for the object in a common coordinate system. A second control module is in data communication with the second imaging device to determine contour information for the object in the field of view of the second imaging device and report the contour information for the object in the common coordinate system.

  • Patent number: 8520219
    Abstract: A non-contact sensing system acquiring three-dimensional information includes a laser light source and fiber generating a Gaussian optical beam. A movable mirror is angularly adjusted to scan the beam to an area of illumination. A lens package between the light source and the movable mirror focuses the optical beam to under-fill a movable mirror optical surface and control an optical beam scanned volume. The optical beam reflected by the movable mirror is redirected using a fold mirror orthogonal to an optical beam orientation. The optical beam is maintained Gaussian by the mirrors and lenses. An imaging device having a field of view intersecting the area of illumination receives optical beam image data reflected from the area of illumination. A control module communicating with the imaging device receives an object location in the imaging device field of view from the image data and reports object location data to a coordinate system.

  • Patent number: 8269828
    Abstract: An imager head assembly for a remote inspection device includes an imager housing. A circuit board is positioned within the imager housing. The circuit board has a light emitting diode connected thereto. A thermally conductive material in contact with the circuit board and the imager housing creates a conductive heat transfer path to dissipate heat generated by the light emitting diode through the imager housing. A light transmissive light pipe unit can be positioned proximate the circuit board to permit light emitted by the light emitting diode to pass through the light pipe unit.

  • Patent number: 8218074
    Abstract: A remote inspection device is provided for inspecting visually obscured locations. The device is generally comprised of a imager housing and a display housing disposed on opposite ends of a modular, flexible cable. An imaging device is embedded in the end of the cylindrical imager housing, such that the imaging device is able to capture an image of a viewing area proximate to the distal end of the flexible cable. One or more light sources also protrude from the outwardly facing end of the cylindrical imager housing along a perimeter of the imaging device such that the imaging device is recessed between the light sources. A display housing is coupled to the other end of the flexible cable and configured to be grasped by a user of the device. A display device supported by the display housing receives a video signal from the imaging device and converts the video signal to a video image.

  • Patent number: 8031345
    Abstract: A sensor system for analyzing a feature in a sensing volume. The sensor system includes a laser source and a sensor. The first laser source projects a laser line into the sensing volume and onto the feature forming a laser stripe on the feature. The sensor images the laser stripe where the laser line intersects with the feature. The relationship between the sensor and the first laser source is precalibrated. The sensor uses the laser stripe to determine the position and/or orientation of the feature.
