Polymer lightguides as optical sensors

Polymer Lightguides of polyimide and amorphous Teflon are used for the measurement of various vapor concentrations ranging from water to organic solvents like acetone. The physical principles of measurement used are monitoring lightguide birefringence and metal film enhanced leaky mode spectroscopy. Dynamic measurements are used in order to also analyze mixed atmospheres.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.
