There are several engineering applications for interferometry where the measurement must be done in-situ in presence of mechanical vibrations or other disturbances. In those cases, optical techniques based in a single image acquisition are the best choices. Approaches like pixelated phase-mask interferometers, instantaneous or simultaneous phase measuring interferometry have been successfully reported in the literature. However, some of them are quite complex or difficult to be miniaturized or made robust enough to be transported and operated in quite hostile environments.
