摘要
提出了利用多曝光数字散斑技术取代干板照相技术记录物体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，给出了物体的面内运动和小角度转动两种运动轨迹的测量结果，对影响实验结果的因素进行了讨论．数字散斑，多曝光照相。
A digital speckle multi-exposure Photographic technique has been Proposed instead of the traditional technique of using photographic plates for the display of motion baths. The Principle of the proposed method has been described in detail in terms of the Young's fringe model. Two experimental results for the lateral motion and the tilt of the measured are been plasented. The factors which affect the measuring results are analysed.
