摘要
根据牛顿环干涉法测量液体折射率时存在的视场模糊不清的实验现象,改进牛顿环装置,获得更加清晰易于观察的干涉条纹,并确保在同一薄膜厚度下测量液体折射率,提高测量折射率的精确度。结合真实可靠的实验图片,对现象分析讨论,进一步说明牛顿环装置改进的合理性。
According to the experimental phenomena of field viewing unclear when measuring refractive index of liquid by New ton ring interferometer ,an improved New ton ring device is provided .It is easy to get a more clear interference fringes observed .And the measurement accuracy of the refractive index is improved at the same condition of film thickness .Phenomena discussed with the real reliable experimental photos ,further illustrate the rationality of New ton ring device improvements .
