Patent number: 8803055Abstract: 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.Type: GrantFiled: January 8, 2010Date of Patent: August 12, 2014Assignee: Automated Precision Inc.Inventors: Kam C. Lau, Yuanqun Liu, Guixiu Qiao, Liangyun Xie

Publication number: 20130342886Abstract: Variable orientation illumination-pattern rotators (“IPRs”) that can be incorporated into structured illumination microscopy instruments to rapidly rotate an interference pattern are disclosed. An IPR includes a rotation selector and at least one mirror cluster. The rotation selector directs beams of light into each one of the mirror clusters for a brief period of time. Each mirror cluster imparts a particular predetermined angle of rotation on the beams. As a result, the beams output from the IPR are rotated through each of the rotation angles imparted by each of the mirror clusters. The rotation selector enables the IPR to rotate the beams through each predetermined rotation angle on the order of 5 milliseconds or faster.Type: ApplicationFiled: October 31, 2011Publication date: December 26, 2013Applicant: APPLIED PRECISION, INC.Inventor: Jeremy R.
