Abstract :
The rotation angle of gas is too minor to measure, so the experiment has to in harsh terms to measure verdet constant. We designed high-accuracy experiment device to measure minor rotation angle based on frequency multiplication method, which makes the verdet constant of gas can be observed at room temperature. Magneto-optical modulation method for optical polarization measurement based on frequency multiplication signal was investigated by means of computer simulation, this method has well applied value.
