Abstract

Differential thermooptic spectroscopy [1,2] involves measuring small differences in the optical absorption of two samples. When exposed to incident light, the two samples will be differentially heated due to their differing absorption efficiencies. Such heating differences will cause a change in their relative indices of refraction. This change can be precisely measured using interferometry [1-4].
