Optical Proximity Sensor based on WGM The challenge: Design a non-contact transduction mechanism for the measurement of linear displacements that is based on the electrostrictive properties (based on the capacitive transducers) of a polymeric optical resonator. The spherical resonator is immersed in a homogeneous electric field that is generated by applying a voltage difference between two metallic plates. One of the plates is fixed, whereas the other one is movable. By changing the distance between the plates, a variation of the electric field intensity occurs, leading to a variation of the mechanical forces (electrostrictive effect) acting on the resonator. This effect, in turn, leads to a change in the morphology of the optical resonator and therefore to a shift of its optical resonances. By tracking the shift of the optical modes, is possible to determine the displacement of the movable plate. kindly find attachments
