Abstract:
Imaging device, which is adapted for optically imaging in a first imaging mode an object (0) to be imaged so as to generate at least one real object image (0I) corresponding to said object (0) andwhich is adapted for optically projecting in a second imaging mode a display Image (DI) so as to generate at least one real projection image (PI) corresponding to laid display image (DI), wherein an optical objective arrangement (10) is provided, wherein said optical objective arrangement (10) or a part thereof is adapted to work in said first imaging mode as an image recording objective or camera objective or as a part thereof, wherein said optical objective arrangement (10) or a part thereof is adapted to work in said second imaging mode as an image projecting objective or projector objective or as, a part thereof, wherein image sensor means (40) is provided for receiving and/or recording said real object image (0I) in said first imaging mode, wherein illumination unit (50) is provided for optically projecting together with said optical objective arrangement (10) said display image (DI) in said second imaging mode in order to obtain said projection image (PI), and wherein a common polarization selective beam splitter device (20) is provided in the optical paths and located between said optical objective arrangement (10) and said image sensor means (40) on the one hand and between said optical objective arrangement (10) and said illumination unit (50) on the other hand in order to couple light for said real object image (0I) from said optical objective arrangement (10) into said image sensor means (40) in said first imaging mode and in order to couple light for said display image (DI) from said illumination unit (50) into said optical objective arrangement (10) in said second imaging mode.
