Take grating diffraction and polarization optics as theoretical foundation second furthermore combined with electronics knowledge to analyze the system. First make use of autocollimation diffraction of grating measurement information obtained by dual-frequency laser belongs to ac signal the interferometer measurement system take grating pitch as measuring datum the structure is simple possess great gain and high signal-noise ratio therefore stable completely overcome the disadvantages of DC level drift caused by light intensity variation of single-frequency laser system can achieve nanometer resolution. 2010 IEEE. reduce the impact of environmental factors easy to install and debug measurement error is small
	A new method of measuring lead screw with dual-frequency laser interference (EI CONFERENCE) 会议论文 OAI收割 2010 International Conference on Computer, Mechatronics, Control and Electronic Engineering, CMCE 2010, August 24, 2010 - August 26, 2010, Changchun, China 作者: Qi X.-D. 收藏 \| 浏览/下载：39/0 \| 提交时间：2013/03/25 A new optical structure of measuring lead screw with dual-frequency laser interferometer is proposed and a formula used quickly correcting Abbe error is deduced in this paper. In the process of testing lead screw Abbe error in the measured data can be real time compensated so that the measurement system which doesn't meet Abbe principle can achieve high measurement accuracy. In addition this method can also eliminate measurement error induced by axial movement of the measured lead screw. The experimental result shows that of the maximum residual error is only 0.48m within 300mm stroke after the maximum Abbe error 1.39m is corrected. This method effectively improves the measurement accuracy of lead screw. 2010 IEEE.
