An interferometer phase-shift measurement system is available from Precision-Optical Engineering. Designed for enhancing the measurement accuracy of optical components and systems, its hardware uses piezo transducers to produce the appropriate phase shifts by moving the reference optic by about λ/2. The included software provides analysis of circular, multiple, low-contrast and nulled fringes, offering repeatability of λ/100. The company says that the device can be used with interferometers from any manufacturer.
