© JMDThèque - 2013

Concerning 3D HDTV, JMDThèque (through BreizhTech) took part in the Futurim@ges Project led by Thomson Multimedia, France Telecom R&D, Alcatel Lucent and others major companies (this project is labelised by the Media & Networks competitiveness cluster). To produce 3D images (not requiring the use of specific glasses), several competing technologies exist at the present time. Among the concepts explored in the Futurim@ges project, the "2D+Z" approach consists in using several image planes to produce a depth effect (combination of a 2D image plane and a depth card according to a Z-plane). In this perspective, the JMDThèque's video projector is an interesting solution through its ability to specifically address each of these planes.

OUR PARTNERS :

Technically it is feasible to make the holographic feature films with normal running time up to 150 minutes, to manufacture on the commercial bases all equipment for holographic movies and to open a holographic movie theater with unlimited number of seats. Now we can say with confidence that this holographic movie system surpasses the regular 35mm and stereoscopic-polarization motion pictures systems by all major parameters, including brightness, sharpness and quality of color.

Application of the JMDThèque's technology to the holographic movie system

Holography is a process of photography in three dimensions using the properties of coherent light produced by lasers.

It produces a hologram in illuminating an object by a coherent source of light (laser) and saving on a sensitive area (for example, a photographic plate) interference fringes obtained by combining the wave emitted by the laser source (Reference wave) and the waves reflected from the object. During the rendition of the holographic image, the hologram is illuminated by a laser and it acts as a diffraction grating, to form a relief image of the original object. An advantage of this technique is that each piece of hologram can return the same image as the entire hologram viewed from a certain angle, sharpness aside, even if the plate is broken. Instead of being produced by a real object, a hologram can also be calculated by a computer from an image in 3D.

JMDThèque revolutionizes the Digital Video Projection




JMDThèque develops a new concept of intelligent digital Video projection with Ultra High Definition, where the light source is provide with laser. With this innovating technology - protected by 6 patents - JMDThèque intends to address several market segments:

- 3D HDTV and Professional Home Cinema Markets,

- Digital Cinema of 2nd Generation with 2D/3D special effects for Multimedia Thematic Theater Market,

- 3G/4G Mobile Phone Terminals, Pocket/Micro PC and PDA Markets, to project images the size of a computer screen.

Application of JMDThèque's Technology to Imaging


We should mention that in recent years, a new branch of holography has been developed: the digital holography. Indeed, thanks to progress in the field of digital cameras and computers, it is now possible to record a hologram on a digital camera, and reconstruct the original object.

The advantage of this technique is the ability to record holograms at video frequencies and thus obtain tridimensional quantitative views of objects in real time. Besides, it was shown that with the introduction of targets microscopes, it is possible to quantitatively represent the form of microscopic objects like cells. Finally, as the reconstruction process is done digitally, it is possible to apply digital processing on the hologram or in the process to improve the quality of images, change the position of the reconstruction plan or compensate aberrations.
