Abstract
The systems and methods include generating polarization-switched (PS) detector and reference signals using a polarization switch controlled by a digital control signal generated by digital input/output card. A gain adjustment is performed on the PS detector and reference signals to define gain-adjusted detector and reference signals. The digital control signal is used to synchronize the gain-adjusted PS detector and reference signals to define gain-adjusted synchronized PS detector and reference signals each having respective steady-state portions. The steady state portions are used to define a measurement signal. The measurement signal is then used to calculate a stress-based characteristic of the sample being measured. The sample can be moved continuously or discretely through different measurement positions, which are synchronized with the operation of the polarization switch using the digital control signal.
