摘要	Grating lateral shearing interferometry is one of important technique to test the system wavefront aberration from lithographic lens. In order to achieve the calibration in ultra-high-precision, we must eliminate the system errors from the grating lateral shearing interferometer. Therefore, a three-step average algorithm and a weighed-three-step average algorithm are proposed to remove the rotationally asymmetric system errors from our shearing setup. The research results show that the RMS of the accuracy of three-step average algorithm centered on 45 degrees can approach 0.71 nm, and the RMS of the accuracy of its weighed algorithm can approach 0.54 nm.
