Paper Abstract

An intensity modulated optical fiber accelerometer is designed. It can be applied in the real-time measurement of dynamic vibration acceleration. The theoretical analysis shows that the relation between the light intensity and displacement can be indicated by the same expression just with the difference in coefficient, though models of the fiber-optic intensity distribution at launching fiber end are different, such as Gaussian distribution, uniform distribution and those midst the upper two. Because of the simpleness of the expression, by means of specific linearization processing for the modulating function, a real-time and undistorted acceleration signal can be obtained. A particular compensation is adopted to avoid the effect due to the static drift of the original distance between the launching fiber end and the reflective surface.
