摘要
对经典光学实验仪器牛顿环进行改进,由光的干涉理论推导了曲率半径计算公式,测出第一干涉暗环半径不同时平凸透镜曲率半径和不确定度.数值拟合表明该法结果可靠,并有较多优点.
The classical optical apparatus Newton ring has been modified, the computational formula has been derived by theory of light interference. Series of curvature radius for convex lens with different radius of the 1st dark interference ring and its uncertainty have been mea-sured. This method has very high reliability and many advantages indicated by the numerical simulation.
