Determination of sensitivity vectors in hologram interferometry from two known rotations of the object.
The fringes generated in holographic interferograms by independent rotations of an object are used to determine the sensitivity vectors of a hologram recording setup. This is done by identifying the fringes observed on the surface of a 3-D object with a fringe vector, which, in turn, equals the vector product of the sensitivity vector with object rotation. These vector relationships are formulated in terms of the projection matrices, and a least square error solution is derived that extracts the sensitivity vectors from the fringe data from two or more known rotations.
