Title (EN) EXTERNAL APERTURING FOR DIGITAL MICROMIRROR DEVICES
(FR) OUVERTURES EXTERNES POUR DISPOSITIFS A MICROMIROIR NUMERIQUE
Abstract: front page image
(EN)A digital micromirror device arrangement (200) and devices using the arrangement are disclosed. The arrangement includes a digital micromirror device (DMD) (210) having an active area (212), a cover plate (220) disposed substantially adjacent to the DMD (210) and having a thickness and a light blocking area (240) having an aperture (242) formed therein. The active area (212) is adapted to receive incoming light (260) and to reflect the incoming light (260) as outgoing light (270). The light-blocking layer (240) is offset from a plane of the active area (212) by at least the thickness of the cover plate (220) and is adapted to block light from passing therethrough. The aperture (242) is dimensioned to produce a beam of outgoing light (270) having desired dimensions.
(FR)L’invention concerne un montage à dispositif à micromiroir numérique (200) et des dispositifs utilisant ce montage. Le montage comporte un dispositif à micromiroir numérique (DMD) (210) présentant une zone active (212), un capot (220) disposé en position sensiblement adjacente au DMD (210) et présentant une certaine épaisseur, et une zone bloquant la lumière (240) dans laquelle est ménagée une ouverture (242). La zone active (212) est conçue pour recevoir la lumière entrante (260) et réfléchir la lumière entrante (260) sous forme de lumière sortante (270). La zone bloquant la lumière (240) est décalée par rapport à un plan de la zone active (212) d’au moins l’épaisseur du capot (220) et est conçue pour bloquer la lumière la traversant. L’ouverture (242) est dimensionnée de façon à produire un faisceau de lumière sortante (270) présentant des dimensions souhaitées.
