Abstract
Description
technical field
[0001] The invention relates to a positioning and supporting device, which is used for supporting and positioning a large precision optical reflection mirror, and is especially suitable for supporting and positioning a main mirror of a large astronomical telescope. Background technique
[0002] Precision optical mirrors need stable and precise support and positioning. For example, in the process of tracking and observing celestial bodies with astronomical telescopes, the mirrors often need to start from the lowest pointing close to the ground level and turn to the highest pointing at the zenith, that is, often need to realize the pitch angle The range is from 0 degrees to 90 degrees, and it is necessary to ensure that the mirror surface always maintains the required surface shape accuracy and positioning accuracy during the tracking process. This requires good positioning and support of all mirrors of the astronomical telescope, especially the primary mirror....
