A phase-sensitive detection technique for measuring fluorescence lifetime has the advantage that the measurement is independent of the intensity of the detected fluorescence signal which is usually a function of several properties of the sample and the environment. However, lifetime measurements require bulky and expensive instrumentation and are more suited to the laboratory. In this paper we report on a low cost, closed loop scheme applied to a fiber optic oxygen sensor. The sensor has all the advantages of lifetime-based sensors as well as the virtue of being small, compact, robust, and economical.
