| 摘 要： | 当满足相干条件时,光波会表现出相干性,在两列光波相遇的区域光强形成稳定的分布。光波的振动方向、光源的单色性都会影响相干条纹清晰程度。本文计算了高斯型频谱分布光源下双光束干涉的光强分布,并得出了气体激光器或单谱线蒸气灯发出的光的非单色性对杨氏双缝干涉的影响可以忽略的结论。

| Abstract: | The coherence characteristic of light will appear when certain condition is satisfied;and steady intensity distribution will get formed in the superposition region.The contrast of fringes would be affected by the vibration direction of light wave and the monochromaticity of light source.In this paper,the interference fringe intensity and visibility of the dual-light beam with Gaussian frequency spectrum is calculated.At last,we obtained the conclusion that the effect of non-monochromaticity on fringes visib... |
