| 摘 要： | 在物理和物理实验教学中,白光干涉是光学部分非常重要的知识点和难点。为了加深学生对白光干涉原理的理解,利用傅里叶变换、色度学原理和matlab软件将白光干涉条纹图分解成彩色的单色光干涉条纹图,从而验证了白光干涉的原理。干涉信号从空域到频域再到空域的转换过程亦可帮助学生理解正、逆傅里叶变换的原理。

| Abstract: | White-light interference is a key point of optics in physics education.Matlab software is used with Fourier transform and coluorometry to decompose the white-light interferogram into monochromatic light interferogram,which helps students understand the principle of white-light interference.The interference signal is transformed from the spatial domain to the frequency domain and back to the spatial domain,which also helps students to understand the principle of Fourier transform. |
