Paper Abstract

A prototype fiber optic fluorosensor for measuring low (radiobiologically relevant) levels of oxygen is described. The fluorescence of an excited fluorophor immobilized in a polymer at the end of an optical fiber is quenched by oxygen. The prototype fiber optic sensor operates most effectively in the 0 - 2% O2 range with fast response and settling times. This approach shows promise in overcoming some of the limitations of existing oxygen sensor systems.
