Abstract

This paper discusses the characteristic of two-fiber, intensity modulated FODS, a type of high sensitivity displacement sensor, from a theoretical prospective, focusing on the geometrical parameters including fiber aperture (NA), radius of fiber core (r), lateral separation of the transmitting and receiving fibers (s), the angle between the two fibers (2a), and the reflector curvature radius (R_c). A mathematical model is set up to investigate the influence on the performance of FODS introduced by the variation of these parameters, and the simulation results are also presented to conduct farther study in this field.
