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
