Abstract
The whole LAMOST(Large-sky-area multi-object fiber spectroscopic telescope) project achieved successfully last year and has observed properly. As the high precision and large scale modern measuring instrument, laser tracker is widely used in various field environment. But in the process of LAMOST building, the measurement requires high precision in most cases especially for focal plane system measuring. This paper mainly focuses on the focal plane measurement, to testify the feasibility for using laser tracker to measure the focal plane plate. And a lot of experiment results and analysis will be mentioned in the paper. There are three laser tracker producers in the world and the main models with the three producers have all compared in detail. Furthermore, the special calibration scheme for the laser tracker will be discussed, and tries to improve the precision and stability of the laser tracker measuring system in the LAMOST field environment.
