Embodiment Construction
[0043] According to a first preferred embodiment, the invention comprises a hybrid projection matrix for stereoscopic projection of three-dimensional (3D) images. The matrix comprises a synergistic combination of at least two different types of particles in an optically transparent solid support:
[0044] comprising a first type of nanoluminescent particles adapted to non-linearly absorb one or two photons and emit visible light; and
[0045] A second type consisting of at least one additive that enhances the nonlinear absorption of one or two photons and the emission of visible light by the nanoluminescent particles, thus making it possible to enhance and / or modify the nanoluminescent particles.
[0046] The matrix is preferably a matrix in which the light-transparent solid support comprises a polymeric support, such as polymethylmethacrylate (PMMA). It should be understood that other polymeric materials that form light transmissive structures may be used in the present in...

Abstract
The invention mainly relates to the field of hybrid nanocomposites for stereoscopic projection, for example in 3D imaging (for example in the field of entertainment or in the field of medicine). In particular, the present invention describes binary hybrid projection matrices comprising at least two types of (nano)particles and / or different molecules (quantum dots, metal nanoparticles, carbon nanotubes), methods for manufacturing the matrices, 3D projection system and method including using a substrate. The addition of a second type of particle makes it possible to modify the properties of the matrix to achieve better stereographic performance or to generate new features not found in individual particles. The new substrate can also reduce the power of the laser used for projection, while achieving brightness equivalent to the existing substrate.
