Abstract

A fiber-optic force and displacement sensor includes a mirror comprising a plurality of sectors extending from a center point to a peripheral edge. Each of the sectors has a high reflectance corresponding to only one of a plurality of single wavelength light beams having different wavelengths transmitted from a laser light source. A method of measuring force and displacement includes measuring the radiant flux between each of a plurality of reflected single wavelength light beams that change as the area of the sectors are displaced towards and away from a center of projection of a combination light beam that comprises the plurality of single wavelength light beams projected towards the center point of the mirror when the mirror is in a rested position. Forces acting upon the mirror are measured as a function of the displacement of the mirror and the transverse and the axial stiffness of a connector.
