    摘要： Utilizing frequency-dependent diffraction (also referred to as dispersion) to determine the angular position of a retro-reflective object within a scanning space. The technique involves dispersing an electromagnetic beam into a scanning space by frequency. If a retro-reflective object is located within the scanning space, the object will retro-reflect a portion of the dispersed beam having a frequency that is associated with the angular position of the retro-reflective object within the scanning space. The frequency of the retro-reflected beam is used to determine the angular position of the retro-reflective object within the scanning space. When a second beam is dispersed into the scanning space and a portion of the second beam is retro-reflected in the manner just described, a second angular position of the retro-reflective object can be found. Coordinates of the retro-reflective object are determinable by triangulation using the two angular positions. These are absolute, as opposed to relative, coordinates.

    摘要： An optical position-tracking system comprises a first light beam steering device for sweeping a first light beam through a first angular range to cause a reflection of the first light beam by a target. Additionally, the optical position-tracking system further comprises a second light beam steering device for sweeping a second light beam through a second angular range to cause a reflection of the second light beam by the target. Moreover, the optical position-tracking system enables determination of a position of the target using a triangulation technique utilizing a first angular value of the first light beam and a second angular value of the second light beam. The first angular value and the second angular value depend on the existence of the respective reflection.

    摘要： An apparatus classifies a material, which may include identifying the material, identifying the type of the material, or identifying the type of the material's surface. The apparatus includes a detector for capturing an image of a surface of the material, and a processor classifies the material by analyzing the image. When incorporated in a mechanism, this apparatus can classify the material on which the mechanism is operating, and, thus, the mechanism can tune some or all of its settings to the material without inconvenience to and with no susceptibility to error by a human operator. For example, when incorporated in a printer, this apparatus can identify the type of media being printed, and, thus, the printer can tune its print settings to the identified media type without relying on operator input.

    摘要： Tracking separation between an object and a surface involves illuminating the surface and reducing the collection angle of light that reflects off of the surface in response to a change in separation between the object and the surface. Reducing the collection angle of light that reflects off of the surface causes the amount of light that is detected to be dependent on the separation distance between the object and the surface. The amount of detected light is then used as an indication of the separation distance.
