摘　　要：提出了利用脉冲多曝光数字散斑技术取代干板照相技术记录物体瞬态运动轨迹的研究方法，根据杨氏条纹模型详细分析了该方法的基本原理，给出了瞬态运动轨迹的测量结果，最后对影响实验结果的因素进行了讨论．A digital speckle pulsed multi-exposure photographic technique has been proposed instead of the traditional technique using photographic plates for the display of transient motion paths. The principle of the proposed method is described in detail in terms of the Young' S fringe model. Experimental result for the transient lateral motion and the tilt of the measured body is presented. The factors which affect the measuring results have been analysed.
