摘　　要：给出测量透镜长焦距的一个方法，该方法的原理是Ｔａｌｂｏｔ干涉。在测量中，根据莫尔条纹的斜角确定正、负透镜的焦距。方法简单，灵敏度可调。A method for measming the long focal length of lens is described in the paper. The principle of the method is based on Talbot interferometry. In the measurements,the focal lengths of positive and negative lens are determined by the tilt angle, of the Moire fringe. The method is simple and the sensitivity can be easily adjusted.
