TLDR
In this paper, a method for increasing the sensitivity of measurements through aberration compensation upon reconstruction of interferograms from two multiple-exposure holograms is proposed, which is tested by visualizing the temperature-field variations in a glass substrate with a conducting coating.Abstract:
A method for increasing the sensitivity of measurements through aberration compensation upon reconstruction of interferograms from two multiple-exposure holograms is proposed. At the early stage of object investigation, the holographic structures recorded at certain time instants are rerecorded by two coherent beams on new image carriers. In this case, the interference moire method is employed to monitor the equality of the vectors of the holographic structures rerecorded. At the final stage, the new nonlinear holograms are processed in an optical analyzer of conjugate holograms with the use of incoherent light. The hologram thus reconstructed offers a high sensitivity of measurements and is free of aberrations. The method is tested by visualizing the temperature-field variations in a glass substrate with a conducting coating.read more

TL;DR: This is an extremely valuable book, which contains much information not readily available elsewhere, and there are gaps in the material which the serious student will find frustrating.

Phase-Difference Amplification by Nonlinear Holograms
TL;DR: In this article, a photographic plate, exposed to fine interference fringes and processed with high gamma, was used to record an amplification of the original phase difference, and the results were shown with a Mach-Zehnder two-beam interferometer.
