Orbital Goniometer Autocollimation Device

Abstract

The present invention relates to an apparatus and method for accurately measure angular deviation of rotating or stationary prismatic elements. The device is based on transferring the accuracy of an external rotating device to the to-be-measured device by building an orbital accuracy transfer system. In order to achieve the required rotational accuracy transfer, the measuring device is positioned on the perimeter of a rotating stage mounted around the to-be-measured part. As a part of the design and disclosed technology, an automation capability measurement will be integrated into the proposed system. Applicable measurements could be performed for satellites, prismatic elements, rotating stages, and many more. The system may comprise an accurately rotating stage or autocollimation theodolite, a reference rotating mirror, an optical bench, and a revolving mechanism for said electronic autocollimation theodolite. For system control, a computer with a special algorithm will be implemented.
