Abstract

In order to study laser Doppler effect, a simple experimental system was set up to measure Doppler effect by means of laser heterodyne interferometer technique.Two sets of experimental data were obtained.At 0.2mm/s of uniform moving velocity,the theoretical and tested beat frequency is 316.0556Hz and 312.0434Hz respectively.At 0.1mm/s of uniform moving velocity,the theoretical and tested beat frequency is 158.0278Hz and 151.6055Hz respectively.Measurement results clearly show the effectiveness of the proposed setup and the simple optical system would be a new and interesting aid for the experiment teaching of classical optics.
