Title (EN) SCANNING OPTICAL SYSTEM AND PROJECTOR PROVIDED WITH SAME
(FR) SYSTÈME OPTIQUE À BALAYAGE ET PROJECTEUR MUNI DE CE DERNIER
(JA) 走査光学系およびそれを備えたプロジェクタ
Abstract: front page image
(EN)Disclosed is a scanning optical system, which has a reduced size and improved accuracy of having an optical component assembled thereto, and furthermore, which has an optical axis easily adjusted. Also disclosed is a projector provided with the scanning optical system. The scanning optical system (10, 20) is provided with: a laser light source section (1) which outputs laser light; a scanning section (2), which has a scanning mirror (3) that two-dimensionally scans the laser light toward the projection surface; and an optical component which guides the outputted laser light to the predetermined direction. The projector (100) is provided with the scanning optical system. The scanning optical system (10, 20) is provided with a projection member (projection prism (81, 83, 84)), which projects the laser light toward the scanning mirror (3), said laser light having been guided by the optical component, and the projection member is fixed on a substrate that constitutes the scanning section (2).
(FR)L'invention concerne un système optique à balayage de taille réduite et de précision améliorée sur lequel est monté un composant optique et ayant en outre un axe optique facile à ajuster. L'invention concerne également un projecteur comprenant le système optique à balayage. Le système optique à balayage (10, 20) comprend : une section à source de lumière laser (1) qui délivre une lumière laser ; une section de balayage (2) qui comporte un miroir de balayage (3) animant d'un mouvement de balayage bidimensionnel la lumière laser vers la surface de projection ; et un composant optique qui guide la lumière laser délivrée dans la direction prédéterminée. Le projecteur (100) est muni du système optique de balayage. Le système optique de balayage (10, 20) comprend un élément de projection (prisme de projection (81, 83, 84)) qui projette la lumière laser vers le miroir de balayage (3), ladite lumière laser ayant été guidée par le composant optique, et l'élément de projection est fixé à un substrat qui constitue la section de balayage (2).
(JA) 小型化することが可能で、且つ光学部品の取り付け精度を向上し、さらに、光軸の調整が容易となる走査光学系およびそれを備えたプロジェクタを得るために、レーザ光を出射するレーザ光源部1と、レーザ光を投射面に向けて二次元走査する走査ミラー3を有する走査部2と、出射されたレーザ光を所定の方向に導く光学部品と、を備える走査光学系10、20およびそれを備えたプロジェクタ100とし、走査光学系10、20は、光学部品により導かれたレーザ光を走査ミラー3に向けて投射する投射部材(投射プリズム81、83、84)を備えていると共に、この投射部材を走査部2を構成する基板上に固定する構成とした。
