The invention relates to fast processing techniques designed for enhancing the pictorial contents of digital holograms, without the need to reconstruct the original 3D scene. The hologram is back-projected to a hypothetical 2D image known as virtual diffraction plane (VDP). The VDP is then processed.....

Success in erbium doped fiber amplifier (EDFA) research has stimulated the development of Er doped glass planar waveguide devices. Planar waveguide components, allowing integration with other optoelectronic devices on the same chip and efficient waveguide-to-fiber coupling, are very attractive for .....

This invention presents light maximization method for LED systems. Derived from a general theory that links the photometric, electric and thermal behaviours of LED systems together, the method provides the rules to design LED systems with maximum light output. Its main contribution is to provide cle.....
