System and method for calibrating optical measurement systems that utilize polarization diversity

摘要

A system and method of calibrating an optical measurement system utilizing polarization diversity is disclosed. A waveplate having a rotation axis is provided. A first light polarization component and a second light polarization component are caused to propagate in the waveplate while the waveplate is rotated about the rotation axis. An equal common phase shift is caused in the first and second light polarization components while a differential phase shift in the first and second light polarization components is maintained. A relative phase between the first and second light polarization components is sensed. At least one calibration parameter is determined based on the relative phase.
