3D holographic video system

Device for presenting 3D animated images, obtained by taking pictures through a diffraction grating, from all size objects, and a projection onto a holographic screen. The diffraction, orientated horizontally, gets by each ray of light a way done which depends on its wavelength and allows to obtain as many angles of vision as wavelengths. The screen diffracts horizontally and works as a complex lens reconstituing an integral 3D effect. Each pixel of the recording support realises a spectrum analysis and, at the time of the projection, return the information. With three recording supports, RGB natural colours are obtained. The data are converted into digital form. The data processing allows to create synthetic three-dimentional images.
