By Pascal Picart,Jun-chang Li

This e-book provides a considerable description of the rules and functions of electronic holography.
The first a part of the booklet bargains with mathematical fundamentals and the linear filtering idea essential to strategy the subject. the following half describes the basics of diffraction concept and exhaustively info the numerical computation of diffracted fields utilizing FFT algorithms. a radical presentation of the rules of holography and electronic holography, together with electronic colour holography, is proposed within the 3rd part.
A particular part is dedicated to the algorithms and techniques for the numerical reconstruction of holograms. there's additionally a bankruptcy dedicated to electronic holographic interferometry with functions in holographic microscopy, quantitative section distinction imaging, multidimensional deformation investigations, floor form measurements, fluid mechanics, refractive index investigations, artificial aperture imaging and data encrypting.
Keys that allows you to comprehend the variations among electronic holography and speckle interferometry and examples of software program for hologram reconstructions also are handled in brief.
