Title (EN) IMAGE PROJECTION DEVICE
(FR) DISPOSITIF DE PROJECTION D'IMAGE
(JA) 画像投写装置
Abstract:
(EN) This image projection device is provided with: an image display element that forms a projection image; a transmission optical system, which is positioned on the light outgoing surface side of the image display element, and which includes a diaphragm and a plurality of lenses; and a reflective optical system that includes a first mirror, which reflects light outputted from the transmission optical system, and which has positive power, and a second mirror, i.e., a planar mirror that reflects light to a projection surface, said light having been reflected by the first mirror. The first mirror is positioned between the second mirror and the projection surface in the direction along the optical axis of the transmission optical system. An intermediate image is formed between the transmission optical system and the first mirror.
(FR) L'invention concerne un dispositif de projection d'image étant pourvu : d'un élément d'affichage d'image qui forme une image de projection ; d'un système optique de transmission, qui est positionné sur le côté de surface de sortie de lumière de l'élément d'affichage d'image, et qui comprend un diaphragme et une pluralité de lentilles ; et un système optique réfléchissant qui comprend un premier miroir, qui réfléchit la lumière émise par le système optique de transmission, et qui a une puissance positive, et un second miroir, c'est-à-dire un miroir plan qui réfléchit la lumière vers une surface de projection, ladite lumière ayant été réfléchie par le premier miroir. Le premier miroir est positionné entre le second miroir et la surface de projection dans la direction le long de l'axe optique du système optique de transmission. Une image intermédiaire est formée entre le système optique de transmission et le premier miroir.
(JA) 画像投写装置は、投写画像を形成する画像表示素子と、画像表示素子の出射面側に位置し、絞りと複数のレンズを含む透過光学系と、透過光学系の出射光を反射する正のパワーを有する第1ミラーと、第1ミラーの反射光を投写面に反射する平面ミラーである第2ミラーとを含む反射光学系と、を備える。第1ミラーは、透過光学系の光軸に沿った方向において、第2ミラーと投写面との間に位置する。透過光学系と第1ミラーとの間に、中間像が結像される。
