| Abstract: | When the angle of an air wedge that is formed by two flat glass plates is changed, the moving interference fringes can be observed by means of CCD. Based on this phenomenon, an optical method is designed in measuring cone angle by the variation of wedge angle which is caused by the deviation of cone angle. The relation between the deviation of cone angle and the number of the moving interference fringes through a certain point can be determined as well as the cone angle. The results verify that the method is feasible and has much higher accuracy than the method of dial gage. |
