| Abstract: | The developement of reflective fiber-optic sensors is introduced in this paper. The hypothesis that the output optical field intensity distribution from the end of a fiber is radially constant within the numerical aperture has been modified, which general be used to analyze the intensity type fiber-optic sensors. The fiber end output optical field flux distribution function was given and the compensation analysis method was established with the example of a compensable reflective type fiber-optic probe. Finally, we have analyzed the temperature stability for this kind of optical fiber sensors. |
