摘要
将传统的迈克尔逊干涉仪进行改装并用于蔗糖溶液折射率的测量,装置采用 OpenMV 摄像头进行干涉条纹的识别,减速电机加步进电机进行位移测量,Arduino单片机进行控制和运算。 改装后的迈克尔逊干涉仪有效缓解了操作过程中的视觉疲劳,减少了读数误差和测量误差。 实验结果表明,所测折射率数据准确,与理论计算结果吻合。 该装置可以广泛应用于大学物理实验,也为进一步工业化应用提供了可行性。

Abstract:
The modified Michelson interferometer is used to measure the refractive index of sucrose solution. The device uses the OpenM camera to identify the interference fringes ,the gear motor and the stepper motorto measure the displacement ,and the Arduino microcontroller to control and calculate.The modified Michelsoninterferometer effectively alleviates the visual fatigue in the operation process and reduces the error. Therefractive index measured by experiments accurate and consistent with the theoretical results. Therefore , thedevice can be widely used in college physics experiments, and also provides potential for further industrialapplications.
