The Large Sky Area Multi-Object Spectroscopic Telescope (LAMOST) is one of the major national projects still under construction in China, which obtained first light in the July 2007. It has two key fundamental technologies, combined thin mirror active optics and segmented mirror active optics, and fiber positioning. This paper introduces briefly the characteristic of the LAMOST active optics wavefront sensing theory, which is very important, and the unique for all the existing telescopes equipped with active optics technology. During the past days, there are many active optics progresses taken place during the LAMOST alignment. Some onsite sensing results are given to show you the wavefront sensing progress and to verify this developed method, which is now successfully adopted and implemented in LAMOST active correction. Finally some conclusions are reached upon the current wavefront sensing method.
