一种灵敏的偏振调制技术使用光弹性调制和外差检测来同时测量由半导体和金属样品透射的光中的法拉第旋转和诱导椭圆率。测量的频率在中红外线，对应于CO2激光器的光谱线。测量的温度范围是连续的，从35到330 K。测量的样品包括GaAs和Si衬底，金和铜薄膜，以及YBCO和BSCCO高温超导体。
A sensitive polarization modulation technique uses photoelastic modulation and heterodyne detection to simultaneously measure the Faraday rotation and induced ellipticity in light transmitted by semiconducting and metallic samples. The frequencies measured are in the midinfrared and correspond to the spectral lines of a CO2 laser. The measured temperature range is continuous and extends from 35 to 330 K. Measured samples include GaAs and Si substrates, gold and copper films, and YBCO and BSCCO high temperature superconductors.
