Abstract

We present a novel approach for short, medium, and long range displacement measurement. This approach is based on the interrogation of the relative phase-shift between two orthogonally polarized sinusoidal optical signals through cross-phase modulation. Displacement determines the power of the side-band generated from cross-phase modulation. Displacement measurement over a range of 12 mm with sub millimeter resolution is demonstrated.
