光频测量的发展

The Development of Optical Frequency Measurement

激光与光栅上衍射的±1级衍射波会合，由于有光程差而发生光拍频，测量拍频信号的相位移则可测得光栅的位移。

As the laser from LD incidents on the diffraction grating and ± 1 order diffraction beams are interfered , if the interferometer has the optical path difference , the optical beat frequency will appear . Measuring phase of beat signal , the displacement of grating will be obtained .
