用剪切干涉条纹测双棱镜的折射棱角

Measuring Wedge Angle of Double Prism by Fringes of Shearing Interference

用激光楔形板剪切干涉，测量干涉条纹的间距，得出了双棱镜的折射棱角。对测量结果进行了讨论，并与劈尖法结果进行比较。

The wedge angle of double prism is obtianed by using the wedge-plate shearing interference and measuring fringe spacingThe measurement result is discussed and is compared to the result of wedge interference
