Abstract
A simple fiber-optic chemical sensor which may be used to detect in-situ and in real time concentrations and chemical transformation of liquids and pastes is reported. The sensor, comprised of a tunable IR diode laser source and a cladding-free multimode IR fiber, operates on the principle of evanescent field absorption spectroscopy. The sensor's response is theoretically analyzed and experimentally verified.
