Paper Abstract

Multi-objects survey system because of its high efficiency have been planned to build in many telescope such as Mayall 4m telescope and have been working well on LAMOST. The telescope could control massively robotic fiber-positioners carried with fibers on the top, received thousand galaxies and quasi-stellar objects at one time observation. How to measure every fiber's position accurately is the key techniques for the telescope to improve its performance. There is a good way to measure the fiber’s position by photogrammetry with no touches measurement. The camera could capture the position of backside illuminated fibers. In this paper we described the trial measurement for multi positioners system in different measuring parameters, and compared these conditions which influenced the measuring accuracy. Finally the test results were presented the baseline parameters for the measurement system to provide a site measurement option for the positioner location.
