    摘要: Systems and methods for position determination and motion tracking for use in a processor based system. Embodiments may incorporate a redirector that moves in at least one direction about a fixed point, an object operable to reflect a search beam as a location beam, logic operable to determine at least one angle of position for the object from the orientation of the redirector, and logic operable to determine a distance of the object from a fixed point.

    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 navigation system for determining movement relative to a navigation terrain includes a first source and a second source of optical radiation for illuminating the navigation terrain, the first source differing from the second source in at least one operating parameter. The system further includes means to select the first source and the second source independently based on decision criteria. The system further includes a detector for capturing patterns in the optical radiation subsequent to illuminating of the navigation terrain.

    摘要: The various embodiments generally describe systems and methods related to 3-dimensional (3-D) imaging. In one exemplary embodiment, an imaging system incorporates a 2-dimensional (2-D) image capture system that generates 2-D digital image information representing an object, a signal transmitter that transmits a ranging signal towards the object, and a signal receiver that receives the ranging signal returned by the object. Also included, is an image processor that computes distance information from the time difference between signal transmission and reception of the ranging signal. The image processor combines the distance information and 2-D digital image information to produce 3-D digital image information representing the object.

    摘要: A method for determining relative movement between an optical navigation device and a navigation terrain includes generating two overlapping coherent optical beams, and generating a pattern of interference fringes between the two overlapping optical beams. The method further includes illuminating a surface portion of the navigation terrain with the pattern of interference fringes, imaging a fringe-illuminated surface portion, and generating a pattern of signals in response to the imaged fringe-illuminated surface portion.
