摘要: We report performance improvement of an optical fibre oxygen sensor based on direct measurement fluorescence quenching sensitive ruthenium complex and indirect lifetime through phase fluorometry. Comparison between detection scheme with without emission filters using various bandpass ranges are being investigated. A 1.7 fold increase in intensity is observed a employing broad (195 nm) filter compared to system filter. Six detected when narrow (25 adopted the system. Similarly, six angle value φω demonstrated in-direct O2 25 nm employed such Improvement sensitivity linearity also reported inclusion
