This ebook offers a considerable description of the foundations and functions of electronic holography.
The first a part of the e-book offers with mathematical fundamentals and the linear filtering concept essential to method the subject. the subsequent half describes the basics of diffraction thought and exhaustively information the numerical computation of diffracted fields utilizing FFT algorithms. an intensive presentation of the foundations of holography and electronic holography, together with electronic colour holography, is proposed within the 3rd part.
A specified part is dedicated to the algorithms and strategies for the numerical reconstruction of holograms. there's additionally a bankruptcy dedicated to electronic holographic interferometry with purposes in holographic microscopy, quantitative part distinction imaging, multidimensional deformation investigations, floor form measurements, fluid mechanics, refractive index investigations, artificial aperture imaging and data encrypting.
Keys to be able to comprehend the diversities among electronic holography and speckle interferometry and examples of software program for hologram reconstructions also are handled in brief.
