摘要
从光源的空间相干性和实际光源的边缘衍射特性两个方面分析给出了干涉、衍射实验中衍射物到光源的距离的估算公式,分析了双缝干涉和?白松亮斑两个实验实例.
The formulae used to estimate the position of the diffraction object in the interference and diffraction experiments are derived through two approaches : analyzing the space coherence property of the source and considering the edge diffraction property of the practical source. The double slits interference experiment and the circle opaque diffraction experiment are analyzed as two examples.
