Paper Abstract

The condition of energy conservation in a two-beam grating interference element imposes a phase shift of m? on the diffraction order m of one of the two incident beams relative to the same order of the other beam. The expressions of the resulting interference products are given and their implications for a diffractive interferometric displacement sensor are discussed.
