Abstract:
(EN) Provided are an optical system, a projection device, and an imaging device, in which projection on discontinuous planes can be performed with no gap, and imaging of the discontinuous planes can be performed with no dead angle. The optical system having an imaging lens 10 that images a first plane and a second plane which are discontinuous, is provided with: a first optical system G1 that images the first plane; a second optical system G2 that images the second plane; and a common optical system GC that forms, in a first light reception region R1 of an image sensor, a subject image incident via the first optical system G1, and that forms, in a second light reception region R2 of the image sensor, a subject image incident via the second optical system G2. The angle of view imaged by the first optical system G1 and the common optical system GC overlaps with the angle of view imaged by the second optical system G2 and the common optical system GC. Further, the optical system having the imaging lens 10 is provided with a first focus-point adjusting unit that adjusts the focus point of an optical system composed of the first optical system G1 and the common optical system GC, and a second focus-point adjusting unit that adjusts the focus point of an optical system composed of the second optical system G2 and the common optical system GC.
(FR) L'invention concerne un système optique, un dispositif de projection et un dispositif d'imagerie, dans lesquels une projection sur des plans discontinus peut être effectuée sans espacement, et une mise en image des plans discontinus peut être effectuée sans angle mort. Le système optique, qui comprend une lentille d'imagerie 10 qui met en image un premier plan et un second plan qui sont discontinus, comprend : un premier système optique G1 qui met en image le premier plan ; un second système optique G2 qui met en image le second plan ; et un système optique commun GC qui forme, dans une première région de réception de lumière R1 d'un capteur d'images, une image objet incidente par l'intermédiaire du premier système optique G1, et qui forme, dans une seconde région de réception de lumière R2 du capteur d'images, une image objet incidente par l'intermédiaire du second système optique G2. L'angle de vue mis en image par le premier système optique G1 et le système optique commun GC chevauche l'angle de vue mis en image par le second système optique G2 et le système optique commun GC. En outre, le système optique comprenant la lentille d'imagerie 10 comprend une première unité de réglage de point focal qui règle le point focal d'un système optique composé du premier système optique G1 et du système optique commun GC, et une seconde unité de réglage de point focal qui règle le point focal d'un système optique composé du second système optique G2 et du système optique commun GC.
(JA) 不連続な平面に隙間なく投影でき、かつ、不連続な平面を死角なく撮像できる光学系、投影装置及び撮像装置を提供する。不連続な第1平面及び第2平面を撮像する撮像レンズ10を有する光学系は、第1平面を撮像する第1光学系G1と、第2平面を撮像する第2光学系G2と、第1光学系G1を介して入射する被写体像をイメージセンサの第1受光領域R1に結像させ、かつ、第2光学系G2を介して入射する被写体像をイメージセンサの第2受光領域R2に結像させ共通光学系GCと、を備え、第1光学系G1及び共通光学系GCにより撮像される画角と第2光学系G2及び共通光学系GCにより撮像される画角とがオーバーラップする。また、撮像レンズ10を有する光学系は、第1光学系G1及び共通光学系GCで構成される光学系の焦点を調節する第1焦点調節部と、第2光学系G2及び共通光学系GCで構成される光学系の焦点を調節する第2焦点調節部と、を備える。
