Fiber-Optic Force Sensor: Mathematical Model, Conversion Function, Prototype Design

Abstract

The article considers the problem of the lack of methods for calculating and selecting design parameters when developing and implementing a fiber-optic force sensor (FOFS) as a separate element or component of the system. To solve this problem, we propose to develop a transform function of the power loss of the optical signal from the bending radius of the fiber under the action of applied forces, linking the features of the optical fiberand physico-mechanical parameters of the base on which the fiber is located. Based on the calculations performed, a variant of the FOFS prototype design is proposed.
