Abstract : The patent describes an apparatus for holding and precisely positioning the two holograms used in dual hologram interferometry. Each hologram can be adjusted in position relative to the other and relative to the reference beam with six degrees of freedmon: three translational along three orthogonal axes and three rotational about these axes. Adjustments are accomplished by piezoelectric micrometers having a resolution of 40 angstroms.
