Abstract

In this paper, we present an integrated fiber optic sensor based on a phase detection technique. The operation principle of the sensor as a xerogel based oxygen sensor has been demonstrated. The integrated device includes a light emitting diode, an oxygen sensing probe and a CMOS Integrated Circuit (IC). The CMOS IC combines the LED driver circuitry, optical detector and the phase detector circuitry on a single chip. The integrated sensor provides accurate, low cost and low power detection for quantifying oxygen and for recording excited-state lifetimes ranging from nanoseconds to milliseconds.
