Research on calibration method of LAMOST fiber robot

Abstract

Large sky area multi-object fiber spectroscopy telescope (LAMOST) is an innovative reflecting Schmidt telescope. One of its key technology is 4000 dual rotational fiber robot located in the focal plane. This article analyzes the calibration requirements of the 4000 fiber robot. And then, proposes a fast calibration method in the complex field environment, and discribes the specific process how to obtain positioning parameters of the fiber robot rapidly.
