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...
