Computer Generated Hologram MATLAB Search and download Computer Generated Hologram MATLAB open source project / source codes from woold.info The algorithm of the MATLAB program is discussed. Using this technique, computer generated holograms can be easily generated in a PC even at undergraduate level. The computer generated holograms were generated and reconstructed using Matlab (version Ra). The main steps to follow in the development of a computer generated hologram and the reconstruction of the object from the hologram is shown in the figure 1. holography,diffraction tomographicholography,and optical scanning holography. Practical applications are discussed, and accompanied by all the theory necessary to understand the underlying principles at work. A further chapter covers advanced techniques for producing computer-generated holograms. Extensive MATLAB. The process of CGH formation was implemented by means of the program developed within MATLAB. a) b) c) Fig. 3. Initial gray scale image of the building of International Studies Centre of Kaunas University of Technology (a), computer-generated hologram (b), and reconstructed CGH (c). INTRODUCTION A hologram is an interference recording of a 3D surface. Upon the proper recording, reconstruction, and viewing conditions, unlike the traditional 2D photography, the image appears to be 3D again. A computer generated hologram or a CGH is a computed interference pattern of such 3D scene.I am trying to perform a fourier transform of a phase mask to reconstruct my original image after having performed the fourier transform and extracting its phase. H = fftshift((fft2(fftshift(I1)))); I2 = fftshift(fft2(fftshift(exp(1j.*angle(H)))));. Book: Analog and Digital Holography with MATLAB The next step transfers the computer-generated hologram to a transparency by means of a plotting or. In this work, Computer generated holograms are implemented using Matlab. Based on the Fraunhofer diffraction formula, the Fourier Transform operation is. COMPUTER GENERATED HOLOGRAMS.

What can he mean?

I apologise, but I need absolutely another. Who else, what can prompt?

It seems to me it is excellent idea. Completely with you I will agree.
