频谱法在光的双缝干涉计算中的应用

Application of the spectrum method in calculation the double slit interference of light

杨氏 ( T.Young)双缝干涉实验在波动光学的创立与发展过程中起着重要作用。本文提出了计算双缝干涉光强分布的新方法频谱法 ,其主要数学手段为傅里叶变换。该方法计算程序规范 ,原则上可以用来普遍地处理光的干涉。

T.Young's double slit interference experi m ent had played an important role in the foundation and development of wave optic s.The paper proposes a new methodthe spectrum method which calculates the distribution of intensity of light in the double slit experiment.Because the calculative program of the method is standard,the spectrum method which cardina l instrument in math is Fourier transform can be used,in principle,to tackle wit h the optical program of both interference and diffraction in general.
