透射光牛顿环装置及条纹性质的讨论

Discussion on Newton's ring by transmitted light and characteristics of fringes

改变牛顿环传统的观察方式,观察透射光的牛顿环.通过增大玻璃平板上表面和透镜凸面的反射率,可提高干涉条纹的可见度.并分析了不同反射率情况下透射光和反射光干涉条纹的性质.

Firstly, Newton's rings of transmitted light are observed, instead of their traditional way of observation. Secondly, the visibility of interference fringes is increased by raising reflectivity of uppersurface of glass plate and convex of plane convex lens. And finally, the characteristics of fringes by transmitted light and by reflected light are analyzed under the conditions of different reflectivity separately.
