Based on FBG sensing,a novel fiber Bragg grating axle counting sensor was developed by utilizing the intensity demodulation technique with a couple of matching fiber Bragg gratings.

By a simple sensor system and the intensity demodulation method of matched fiber Bragg grating, the fiber Bragg grating strain sensor is studied theoretically and experimentally.

In this paper, A new technique for the nultiplexing of intensity modulated optical fiber point sensors using TDM technology and a frequency domain approach is proposed.

Optimum design of the modulator in the novel spectropolarimeter based on intensity modulation;

In a reflective fiber optic displacement sensor, the influence on intensity modulation property caused by the reflector shape was studied theoretically with the mathematic model found.

Among the theoretical and experimental research of the reflective intensity modulated fiber optic sensor (RIM FOS), a very important problem is always neglected, which is the effect on the intensity modulation caused by perpendicularity between the axis of fiber pairs and the reflector, i.
