Increase in the sensitivity of holographic reverse shearing interferometry due to the combination of object rotation with optical processing of holograms

摘要

It is shown for the holographic reverse shearing interferometry, which is used in investigations of phase objects with limited sizes, that combination of rotation of the object under study during hologram recording with subsequent optical processing of a pair of matched holograms makes it possible to obtain, with a much higher sensitivity, aberration-free interference patterns reflecting the changes in the wavefront induced by the object studied. The results of the experimental testing of the proposed method for the cases of optical processing of matched and optically conjugate reverse shearing holograms are reported.
