%X The different incident angle and measurement angle in velocity interferometry used are classified, the influence of the angle of the incident laser and reflect laser on the results is discussed. The experiments are designed and dymanic testing is carried out. The experiments results are agreed well with the theoretic analyzing. It shows that the velocity measured under tilting goes smaller than the true velocity of the target. To the one dimension movement, the true velocity of the target can be gotten by the experimental results divided by the cosine of the measuring angle. The other factors, such as the diameter of the collecting lens, bring the influence to the results just within 1%.
