| Abstract: | The main reasons causing larger error by a traditional method measuring the light distribution law of diffraction are pointed out. The principle, the experiment device and the adjustment requirements with a CCD apparatus collecting the light distribution law of diffraction are introduced. The diffraction light distribution curves of the single seams and double seams with different width are obtained. The relative light and relative light distribution of them are calculated. Comparing with the theoretical value, the relative errors are obtained. |
