| 摘 要： | 利用适当的装置产生一定的干涉图样，观察其中条纹的形状、位置和间距及其变化。干涉图样中条纹的形状、位置及间距，取决于光束在各点的光程差以及光波的光谱分布和光源的大小。一般由点光源产生的干涉图样是非定域的，由扩展光源产生的干涉图样则是定域的。

| Abstract: | Using the suitable equipment, certain interference pattern were obtained.The shape, the position, the spacing and the change of these stripes were observed. The results show that these observed parameters were decided by the light beam in each light path difference as well as the light wave spectrum distribution and the photo source size. Interference pattern produced by the point source was generally no nlocalized, nevertheless, the interference pattern by the expansion photo source was the localization. |
