Abstract

An alternative to the conventional linear phase shift in optical testing interferometers is a sinusoidal phase shift, which has the benefit of relaxing requirements on the phase-shifting mechanism. We propose new phase-demodulation algorithms and provide sensitivity analyses to random noise, nonlinearity, vibrations and calibration error to demonstrate that sinusoidal phase shifting can be as robust and computationally efficient as the more established linear phase-shift techniques.
