Abstract

The reflective intensity-modulated fiber optic sensor for measuring displacement, the antenna-shaped fiber optic sensor, is usually composed of a fiber bundle with the emitting and receiving fibers in a specific arrangement at the probe tip. The three elementary types of fiber arrangement are: concentric distribution, semicircular distribution and random distribution. In comparison with the size of the fiber optic sensor, the thickness of clad and binding element of the fibers is so small that it can be ignored. The mathematical models of the modulation function for the single fiber couple which is composed of both an emitting fiber and a receiving one have once been presented. Analyzing the distribution of the fibers inside the fiber optic sensor by using the geometric and statistical theories, the general mathematical models of modulation function for the three types of the sensors mentioned above have been proposed. And all the models are simulated with computer and all the simulating results are briefly analyzed.
