Displacement sensor based on Kerr induced phase-modulation of orthogonally polarized sinusoidal optical signals. | LitMetric

We present a novel short, medium, and long range displacement sensor using a Kerr phase-interrogator. Displacement induces relative phase variation between two orthogonally polarized sinusoidal optical signals. The Kerr phase-interrogator converts the phase variation into power variation through Kerr induced phase-modulation. Displacement sensing over a range of 12 mm with micron level resolution around the quadrature points is demonstrated.
