摘要
在牛顿环等厚干涉现象中,为了研究透镜曲率半径对干涉圆环半径和相邻暗环或明环间距的影响,揭示干涉圆环半径和相邻暗环或明环间距随干涉级次的变化规律,通过理论计算及数值分析,表明干涉圆环半径随干涉级次单调递增,相邻暗环或明环间距随干涉级次单调递减,并且均与透镜曲率半径的大小有关.
In the equal thickness interference phenomenon of Newton ring,in order to study the influence of the radius of curvature of the lens on the radius of the interference rings and the spacing of the adjacent dark rings or the bright rings,reveal the variation of the radius of the interference rings and the spacing of adjacent dark or bright rings with the interference level.Through theoretical calculations and numerical analysis,shows that the radius of the interference rings increases monotonically with the interference level,and the adjacent dark rings or bright rings spacing decreases monotonically with the interference level,and both are related to the radius of curvature of the lens.
