Electronic holography and electronic photo processing are twins born by means of machine period. They proportion starting place, theoretical base, tools and algorithms. the current booklet describes those universal basics rules, equipment and algorithms together with picture and hologram digitization, facts compression, electronic transforms and effective computational algorithms, statistical and Monte-Carlo equipment, photograph recovery and enhancement, photograph reconstruction in tomography and electronic holography, discrete sign resampling and photo geometrical modifications, exact measurements and trustworthy aim localization in photos, recording and reconstruction of desktop generated holograms, adaptive and nonlinear filters for sensor sign perfecting and photo recovery and enhancement. The booklet combines idea, seriously illustrated functional tools and effective computational algorithms and is written for senior-level undergraduate and graduate scholars, researchers and engineers in optics, photonics, opto-electronics and digital engineering.

30) a(x)= fa(f}p(x,f)df It is quite natural to extend this approach to the definition of a(J) by introducing reciprocal functions (J,x), to obtain an analog of Eq. 31) The function a{f) is called the integral transform of signal a{x), or its spectrum, over continuous basis { (f, x)} called transform kerne!. 32) where o(x,~)= f ( / , x), or, in other words, of invertibility of the integral transform of Eq.

Lim{2F sinc[21tF(x -~ )ll. 48) -F is an analog of sinc-function of Fourier transform (Eq. 7). We will refer to it as to frine-funetion. i. 49) 0 known in mathematicalliterature as Fresnel integral ([19]). The relationship between frinc-function and Fresnel integral is described by the formula: Fresnel transform can also be regarded as a convolution transform and it can also be linked with Fourier transform through the convolution theorem. Fresnel transform a Fr lf) of a signal alx) can be found as inverse Fourier transform 2.
