• Optical polarimeter
• Faraday magneto-optic effect
• Signal width measurement

For the optical polarimeter based on the structure of polarizer Faraday modulator analyzer, a novel method of optical rotation measurement was proposed by the waveform analysis of optical intensity signals. The calculation method of the optical rotation was provided by measuring the signal width of the waveform. Furthermore, the optical rotations of sugar solutions with different concentrations were measured by this method, and the fitting degree of obtained fitting curve is 0.9996. This showed that this method was effective.
