Paper Abstract

A novel compensation technique for polarization-modulated optical fiber sensors is proposed, which employs a single LED to provide the measurement and the reference signals. In the sensor head, a polarization beam splitter is used not only as a polarizer, but also as an analyzer, and the reflective structure is used so that the sensor head is simple, compact and reliable. A loss-compensated temperature sensor based on the thermal effect of birefringent crystal is demonstrated. The experimental results show that this compensation technique can stabilize the sensor output with a high accuracy and better long-term stability.
