This paper describes a fiber-optic oxygen sensor using fluorescence and its application to clinical examinations. The quenching ratio of fluorescence is proportional to oxygen partial pressure by Stern-Volmer's formula in which oxygen concentration is estimated from measured emission intensity. We fabricated a microscopic luminous probe using a Solvent Green 5 doped plastic optical fiber coupler. The probe was studied as an oxygen sensor in visible light. We also clarified sensor characteristics.
