Abstract

The Zernike modal wavefront reconstruction error of Shack-Hartmann sensor on measuring the atmospheric disturbed wavefront was analyzed in this paper. It's showed that the wavefront reconstruction error is concern with sub-aperture configuration type and the total Zernike mode number used in wavefront reconstruction algorithm. Some formulas to calculate the wavefront reconstruction error of a Shack-Hartmann sensor in Kolmogorov turbulence were deduced in this paper too. The experiment data from two Shack-Hartmann sensors with configuration of 8x8 sub-apertures and 32x32 sub-apertures respectively were analyzed and compared.
