Cavity ring down (CRD) spectroscopy is an optical spectroscopic technique that measures the absolute extinction by absorption or scattering of samples. It uses highly reflective mirrors, often with reflectivities > 99.9%, to achieve effective optical pathlengths through the sample of tens or even hundreds of kilometers.

Surface Applications of Cavity Ring-Down Spectroscopy | NIST
Abstract We report preliminary results descri two new applications of cavity ring-down spectroscopy (CRDS): 1) detection of non-absor species by refractive-index change using surface-plasmon-resonance (SPR)-enhanced CRDS, and 2) C-H overtone detection by evanescent wave CRDS with a determination of absolute adsorbate surface coverage.
