Paper Abstract

An optical fiber fluorescence sensor system capable of compensating fiber bending loss is presented. The system utilized a modulated light-emitting diode and digital-signal processing chips to enhance the measurement of fluorescence signals. A fiber-optic oxygen sensor system suitable for measuring oxygen levels in gas and in aqueous media was developed, and the capability of the system to alleviate fiber bending loss was demonstrated. The signal-to-noise ratio of the system was found to exceed 30 dB using inexpensive components.
