摘　　要：指出了测量衍射光强分布规律的传统方法 (即螺杆带动光电池法 )产生较大误差的主要原因 ,介绍了利用CCD器件对衍射光强分布进行采集的原理、实验装置和调试要求 ,得到了不同缝宽的单缝和双缝衍射光强的分布曲线 ,计算了这些光强分布曲线的相对光强和相对光强分布 ,并与理论值比较 ,求出了相对误差。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.
