Abstract
The condition of energy conservation in a two-beam grating interference ele ment imposes a phase shift of m pi on the diffraction order m of one of the two incident beams relative to the same order of the other beam. The expre ssions of the resulting interference products are given and their implicati ons for a diffractive interferometric displacement sensor are discussed.
