Abstract

In this paper, we propose a novel scheme of fiber Bragg grating interrogation by use of hybrid fiber optical bistable device (OBD). The OBD is realized in the fiber Bragg grating (FBG) sensing element. Light source is an electronic tuned widely swept ring fiber laser. In this experiment, FBG's are acting as optical intensity modulator and sensing elements at same time. Combined with feedback control circuit, the OBD can be used as an optic-fiber sensor working in digital type through bistable switching phenomenon. We discuss the mechanism of this bistable sensor. Scanning the bias Voltage on PZT, the bistable pulse signal can be counted by circuit that operates in the manner of a pulse-equivalent. If we use 16 bit Digital Analog Converter (DAC), the resolution will achieve 1pm level. High accuracy, high speed and high ratio of signal to noise are the advantages of this scheme.
