摘要
将单片机、摄像头、步进和减速电机等模块添加到传统的迈克尔逊干涉仪上进行改进,基于 Open CV 图像识别技术进行干涉条纹识别,使用改进后的迈克尔逊干涉仪测量乙醇溶液在不同温度下的折射率,并拟合出折射率与温度的关系式。实验验证,改进后的装置使用方便,测量准确。拟合后的曲线较好地反映乙醇溶液折射率随温度的变化关系,可以为科教、工业等领域提供数据参考。

Abstract:
Adding modules such as MCU, camera, the gear motor and stepper motor to the traditional Michelsoninterferometer to improve it, the improved Michelson interferometer is used to measure the refractive index ofethanol solution at different temperatures. Based on Open CV image recognition technology, the number offringes is identified and the relationship is obtained by the least squares fitting.Experimental results show thatthe improved device is easy to use and accurate in measurement. After data fitting, the relationship between thetemperature and refractive index of ethanol solution is obtained , providing referenee data for seienee, industryand other fields.
