Title (EN) AN IMAGE PROJECTING DEVICE AND METHOD
(FR) DISPOSITIF ET PROCEDE DE PROJECTION D'IMAGES
Abstract: front page image
(EN)An image projecting device and method are presented. The device comprises a light source system operable to produce a light beam to impinge onto an active surface of a spatial light modulator (SLM) unit formed by an SLM pixel arrangement; and a magnification optics accommodated at the output side of the SLM unit. The light beam impinging onto the SLM pixel arrangement has a predetermined cross section corresponding to the size of said active surface. The SLM unit comprises first and second lens' arrays at opposite sides of the pixel arrangement, such that each lens in the first array and a respective opposite lens in the second array are associated with a corresponding one of the SLM pixels
(FR)La présente invention concerne un dispositif et un procédé de projection d'images. Le dispositif comprend un système de source lumineuse conçu pour produire un faisceau lumineux qui vient en contact sur une surface active d'une unité de modulateur de lumière spatial (SLM), constituée d'un ensemble de pixels de SLM, ainsi qu'un système optique d'agrandissement, logé côté sortie de l'unité de SLM. Le faisceau lumineux qui vient en contact sur l'ensemble de pixels de SLM présente une section transversale prédéfinie, qui correspond à la taille de ladite surface active. L'unité de SLM comprend des premiers et des seconds ensembles de lentilles sur les côtés opposés de l'ensemble de pixels, de façon que chaque lentille du premier ensemble et une lentille respectivement opposée dans le second ensemble soient associées avec un pixel correspondant des pixels de SLM.
