Abstract
We demonstrate in theory and experiment the use of a reflective Fabry-Perot interferometer to precisely determine the far-infrared reflectance of smooth metal surfaces. The absorption loss in the metal is amplified and thus conveniently measuredon resonance whereas the 100% reflectance reference is takenoff resonance. Absolute accuracy of ±0.1% is achievable.
