N2 - An electro-optic heterodyne interferometer based on phase-locked extraction for measuring low optical rotation angle is successfully developed. The validity of the proposed design is demonstrated by a half-wave plate with the average relative error of 0.74%. When applied to the measurement of glucose solutions with concentrations ranging from 0 to 1.2 g/dl, the average relative error in the measured rotation angle of glucose solutions is determined to be 1.46%. The correlation coefficient between the measured rotation angle and the glucose concentration is determined to be 0.999991, while the standard deviation is just 0.00051 degrees. Overall, the current proposed system is capable of measuring glucose concentration as low as 0.01 g/dl with an error of 6.67%.
