Title (EN) MICRO-PROJECTION DEVICE WITH ANTI-SPECKLE VIBRATION MODE
(FR) DISPOSITIF DE MICRO-PROJECTION AYANT UN MODE VIBRATOIRE CONTRE LES MOUCHETURES
Abstract: front page image
(EN)A micro-projection system for projecting light on a projection surface, comprising: -at least one coherent light source (101); -optical elements (102, 108, 109) in the optical path between said coherent light source and said projection surface; -said optical elements including at least one reflective member (102) actuated by a drive signal for deviating light from said light source so as to scan a projected image onto said projecting surface; -said optical elements including at least one vibrating element (102) actuated by a vibrating signal so as to reduce speckle onto said projecting surface. The corresponding method for reducing speckle is also provided.
(FR)La présente invention se rapporte à un système de micro-projection permettant de projeter une lumière sur une surface de projection. Ledit système comprend : au moins une source de lumière cohérente (101) ; des éléments optiques (102, 108, 109) dans le trajet optique entre ladite source de lumière cohérente et ladite surface de projection ; lesdits éléments optiques comprenant au moins un élément réfléchissant (102) actionné par un signal d'entraînement pour dévier la lumière provenant de ladite source de lumière de manière à balayer une image projetée sur ladite surface de projection ; lesdits éléments optiques comprenant au moins un élément vibrant (102) actionné par un signal vibrant de manière à réduire les mouchetures sur ladite surface de projection. La présente invention se rapporte également à un procédé correspondant permettant de réduire les mouchetures.
