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.

Moreover, the optical position-tracking system further comprises a light beam steering device for sweeping the incident light beam through an angular range to cause a reflection of the incident light beam by a target, whereas the reflection of the incident light beam is directed to interfere with the reference light beam to form an interference light beam. Additionally, the optical position-tracking system enables determination of a position of the target using an interferometric technique utilizing an angular value of the incident light beam and the interference light beam, whereas the angular value depends on the reflection.

Moreover, the optical position-tracking system further comprises a light beam steering device for sweeping the incident light beam through an angular range to cause a reflection of the incident light beam by a target, whereas the reflection of the incident light beam is directed to interfere with the reference light beam to form an interference light beam. Additionally, the optical position-tracking system enables determination of a position of the target using an interferometric technique utilizing an angular value of the incident light beam and the interference light beam, whereas the angular value depends on the reflection. If the light beam has a plurality of wavelengths, either due to the existence of these wavelengths simultaneously, or over a time interval having multiple wavelengths, the absolute position of the target can be determined. If the light beam has a single wavelength, the relative position of the target can be determined.

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.
