Abstract

The J₁... J₃ is a recent optical method for linear readout of dynamic phase modulation index in homodyne interferometers. In this work, the J₁... J₃ method is applied to measure voltage in an optical voltage sensor. Based on the classical J₁... J₄ method, the J₁... J₃ technique shows to be more stable to phase drift and simpler for implementation than the original one. The sensor dynamic range is enhanced. The agreement between theoretical and experimental results, based on 1/f noise, is demonstrated.
