【Abstract】 Frequency shift of the double grating is considered and confirmed by our experiment. Using this effect we determine the value of velocity or small displacement. It is simpler than the method of Michelson’s instrument or the intensity modulating method and has been suceessully tested on Mossbauer spectrometer to determine the velocity of vibration. Satisfactory result has been obtained.更多还原
