摘　　要：提出了一种利用数码相机实现双棱镜干涉实验的方案.利用数码相机替代传统实验中的测微目镜观察并记录干涉条纹和双缝像,再利用Matlab等软件测出干涉条纹间隔及双缝距离.该方案不仅可验证双缝干涉原理,还可以验证平行光干涉原理.通过实验验证了实验方案的可行性,并讨论了利用数码相机进行双棱镜实验的特点和优势.A scheme of biprism interference experiment using digital camera is proposed.A digital camera was used instead of a traditional micrometer eyepiece to observe and record interference fringes or Double-Slit images,and software such as Matlab was used to measure the interference fringes and Double-Slit distances.The scheme can verify the principle of Double-Slit interference and the interference principle of two plane waves.The feasibility of the scheme is verified by experiments,and the characteristics are discussed.
