Holographic microscopy with conjugate reconstruction for the interferometric determination of three-dimensional displacement is described. Three double-exposed holograms for different illumination directions recorded on one holographic plate are reconstructed conjugately, and spatial heterodyne technique was used to evaluate the interferograms. Only by conjugated reconstruction it is possible to obtain a perfectly optimized interferometer for the static evaluation method. The evaluation of strongly disturbed interferograms by speckle noise can be performed successfully. A comparison of the spatial heterodyne with the phase shift technique is given.
