| 摘 要： | 分析了激光的双光栅移频效应,并作了实验验证.这一效应可用来测量小位移量或速度值,比表氏干涉仪简单易调,并已试用于穆氏谱仪上测定振动速度,效果理想.

Double grating frequency shift effect of the laser beam and its application |
| |
| 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. |
