摘　　要：葡萄糖浓度是溶液的主要参量之一。根据葡萄糖溶液的旋光效应,结合电机调制检偏器,通过双光路同步检测,测量两路调制信号的相位差从而得到待测葡萄糖溶液的浓度。实验结果表明:对于浓度范围为0%~50%(质量分数)的葡萄糖溶液,测量最大相对误差约为6.48%。本设计解决了旋光角度测量受机械转动装置限制的问题,测量装置具有结构简单、测量快捷、抗干扰性强等优点。The glucose concentration is one of the main effect of glucose solution, motor modulation analyzer characteristics of solution. Based on the optical rotation and dual light path simultaneous detection, glucose concentration is obtained from the phase difference of the two modulation signals. Experimental results show that the maximum relative error is about 6.48% with glucose concentration from 0% to 50% （mass fraction）. The proposed method solves the problem that rotation angle measurement is limited by mechanical rotation equipment. The measurement equipment has the advantages of simple structure, rapid measurement and strong anti- interference.
