This paper focuses on two aspects. The first aspect aims at the phenomenon of “burr” which influ-ences the photo-beat wave pattern in the experiment of laser dopper effect. The other aspect centers on the problem of “envelope” which brings errors to the number of the wave pattern in terms of calculation. By impro-ving the experiment facility,this paper puts forward suggestions to eliminate the problem of “burr”,optimizes the experiment’ s adjustment methods and reduces the“envelope” problem. Therefore,the experiment’ s accu-racy is improved and thus works quite well.
