Accurate Reflectivity Measurement of High Reflective Mirrors via a Cavity Ring down Method

介绍了利用光腔衰荡光谱技术高精度地检测高反镜的反射率的实验方法。利用直型和折叠型衰荡光腔结合，可以高精度地测定高反镜的反射率。实验结果表明这一方法可以精确地测定各种反射角度、镜片基底和尺寸的高反镜的反射率。

This paper describes measurement of mirror reflectivity via cavity ring down spectroscopy. The method can accurately determine the reflectivity of a mirror, using combination of linear and folded cavities. Results show that this method can measure reflectivity of mirrors of different sizes and media, at any reflection angles, possibly, under working circumstances.
