Abstract
As is known to all, the LAMOST active optics wavefront test is realized by Shack-Hartmann Wavefront Sensor. But because of the characteristics and difficulties of the LAMOST, it is the key problem in the design of LAMOST Shack-Hartmann Wavefront Sensor to select and decide the sampling point number corresponding to one segment of LAMOST.

In this paper we mainly discuss the sampling point number experiment by simulating different numbers of Shack-Hartmann sampling points from one LAMOST segment based on the Large Aperture Active Optics Experiment Telescope Device, which is briefly introduced with LAMOST. After the introduction, the main contents of this article are given including the following three experimental analysis parts. The first experimental analysis is the active optics tests, active optics close loop corrections and comparisons among experiments with different sampling point numbers.

The second is the fitting and correction of the low-frequency aberration items existing in the system with about twenty sampling points. The last is that the low-frequency aberrations such as astigmatism and defocus are generated and then corrected with only twenty sampling points after close loop correction with all sampling points. Finally some primary conclusions of LAMOST Shack-Hartmann Wavefront Sensor sampling point number are reached and given.
