Title (EN) POLARIZED PROJECTION ILLUMINATOR
(FR) DISPOSITIF D'ÉCLAIRAGE À PROJECTION POLARISÉE
Abstract: front page image
(EN)The present disclosure relates generally to an optical element, a light projector that includes the optical element, and an image projector that includes the optical element. In particular, the optical element provides an improved uniformity of light by homogenizing the light with lenslet arrays, such as "fly-eye arrays" (FEA). The FEA is positioned to homogenize a polarized combined light after an unpolarized input light is converted to a single polarization state.
(FR)La présente invention concerne de façon générale un élément optique, un projecteur de lumière qui comprend l'élément optique, et un projecteur d'image qui comprend l'élément optique. En particulier, l'élément optique produit une uniformité de lumière améliorée en homogénéisant la lumière au moyen des groupements de petites lentilles, tels que des « groupements en œil d'insecte » (FEA). Le FEA est positionné de façon à homogénéiser une lumière combinée et polarisée après qu'une lumière d'entrée non polarisée ait été convertie en un état de polarisation unique.
