The large dispersive properties and the narrow frequency bandwidth of the two-wave mixing in a liquid-crystal light valve is used to realize an adaptive holographic interferometer in the Raman–Nath regime. We report experimental observation of picometer periodic displacements and estimate the theoretical signal-to-noise ratio and the minimum quantum-noise-limited detectable displacement.
