  • Patent number: 8803055
    Abstract: A volumetric error compensation measurement system and method are disclosed wherein a laser tracker tracks an active target as the reference point. The active target has an optical retroreflector mounted at the center of two motorized gimbals to provide full 360 degree azimuth rotation of the retroreflector. A position sensitive detector is placed behind an aperture provided at the apex of the retroreflector to detect the relative orientation between the tracker laser beam and the retroreflector by measuring a small portion of the laser beam transmitted through the aperture. The detector's output is used as the feedback for the servo motors to drive the gimbals to maintain the retroreflector facing the tracker laser beam at all times. The gimbals are designed and the position of the retroreflector controlled such that the laser tracker always tracks to a pre-defined single point in the active target, which does not move in space when the gimbals and/or the retroreflector makes pure rotations.

  • Patent number: 8477419
    Abstract: According to various embodiments, a telescope is automatically aligned without requiring user intervention and without requiring knowledge of actual local time or location. A mount model specifying a relationship between a telescope's internal coordinate system and a celestial coordinate system is generated using an arbitrary time, arbitrary telescope location, and a number of alignment reference points. A pointing error for the initial mount model is determined, for example using a plate solving technique to translate between plate coordinates and celestial coordinates for the alignment reference points. Time and location values are iteratively adjusted to reduce the pointing error until it is acceptably low. In one embodiment, adjustments are made by reference to a local sidereal time (LST) offset and/or a latitude value. In one embodiment, the iterative adjustment is performed using a two-phase methodology, including a coarse adjustment followed by a fine adjustment.

    Abstract: A laser spot tracker comprising a quadrant detector. A portion of a spot of laser light reflected from an object being illuminated (OBI) may be defocused to occupy a significant portion such as one-third of the field of view, while another portion remains focused, therefore allowing for quick calculation of the spot centroid. With such a “composite spot”, multiple target (OBI) positions may simultaneously be defined in elevation and azimuth with respect to null by analyzing the energy in each quadrant. The X and Y angle information (off null) for multiple targets (OBIs), and their codes may be displayed. For a large, defocused spot, two segmented multi-element detectors may be used, one in front of and the other behind the focal plane to reduce the effects of hot spots in a spot of laser light collected from an object being illuminated.

The measuring module has an emitting deice, which may emit at least one light ray; the photodiode may receive the incident ray. Also, the trajectory of the incident ray is parallel with the direction of measurement. If there is no geometric error, the position of the incident light ray will coincide with the position of the measured light ray. If there is a geometric error, the position of the measured light ray will not coincide with the position of the incident light ray. After the data are processed and calculated, geometric errors in straightness, squareness and rotational angles (pitch, yaw and roll) may be obtained. These geometric errors may then be corrected in the setup of a machine.

  • Patent number: 7508514
    Abstract: A laser beam may be used to provide a virtual reference axis of travel for the in-axis direction of motion of lenses in a zoom assembly to be positioned during a zoom operation. The virtual reference axis is projected along the optical axis, parallel to existing mechanical lens slides. The virtual reference axis passes through an aperture on each of the lens assemblies, and is sampled by a set of optics and detectors on each of the lens assemblies. The optics and detectors are arranged such that any change in the position of a lens cell within a lens assembly relative to the virtual reference axis is sensed and corrected using a feedback signal to a positioning motor. Since the same virtual reference axis is used for each lens in the zoom assembly, each lens can be independently corrected for off-axis position errors to very high precision.

  • Patent number: 7456943
    Abstract: The position of an apparatus moving along a surface is determined by calculating a plurality of vertical angles between the apparatus and a known location, where the vertical angles vary only within a range having a largest expected maximum angle. A plurality of horizontal distances between the apparatus and the known location are determined, each of the horizontal distances associated with one of the vertical angles. The horizontal distances are computed to within a tolerance based at least in part on the largest expected maximum angle. A plurality of heights of the apparatus are then determined using the plurality of vertical angles and associated horizontal distances. In particular embodiments, the known location may be associated with a rotating laser used with a photodetector at the target to determine the vertical angle. Further, the target may comprise a GPS receiver for use in determining the horizontal distance measurements.
