摘要： A polarization separation device has a grating having a recurring blaze-shaped grating pattern formed on one surface of a transparent base plate and an optically anisotropic material layer arranged adjacent to the grating and having different refractive indices in the direction in which the grating pattern recurs and in the direction perpendicular to that direction. The polarization separation device separates light incident thereon into two linearly polarized light components that have polarization planes perpendicular to each other in accordance with the polarization directions thereof by refracting one and simply transmitting the other of those two linearly polarized light components. Here, the refractive index N0 of the grating and the refractive indices Ne and Np of the optically anisotropic material layer with respect to one and the other, respectively, of the linearly polarized light components are defined as follows: |Ne−N0|≧0.2, and |Np−N0|≦0.03.

摘要： A camera is capable of switching normal photographing mode and panoramic photographing mode to each other and has a view finder for checking a photographing range. The view finder includes a visual frame display device, a device for varying magnification of the view finder, a control device. The visual frame display device switches a visual frame for displaying the normal photographing mode and a visual frame for displaying the panoramic photographing mode. The control device switches the visual frame display device from the visual frame for displaying the normal photographing mode to the visual frame for displaying the panoramic photographing mode and allows the magnification varying device to increase the magnification of the view finder. Instead of the control device, in switching the normal photographing mode to the panoramic photographing mode, the control device also instructs the magnification varying device to vary the magnification of the view finder so that either an angle of view corresponding to a horizontal direction or in a vertical direction in the panoramic photographing mode is displayed in the visual frame for displaying the normal photographing mode and then, instructs the visual frame display device to switch the visual frame for displaying the normal photographing mode to the visual frame for displaying the panoramic photographing mode, and the view finder magnification varying device to vary the magnification of the view finder.

摘要： A rear projector for performing image projection includes: a screen and a projection optical system. The screen has a rotationally symmetric Fresnel lens. The projection optical system has at least one reflection surface formed of a rotationally asymmetric free curved surface. The projection optical system is nonaxisymmetric and makes a central principle ray incident obliquely on the screen in the image projection. The Fresnel lens has aberration that cancels out pupil aberration of the projection optical system so that principal rays of beams exiting from the Fresnel lens become substantially parallel to each other.

摘要： An oblique projection optical system is compact as compared with the size of the image it presents, offers high imaging performance, produces satisfactorily small distortion, and has a small f-number. The oblique projection optical system is composed of a plurality of powered reflection surfaces, of which the one closest to the projection surface is positively powered and the one second closest thereto is negatively powered. At least one of these two reflection surfaces is a free-form surface, and the one closest to the projection surface has a size larger than half the size of the projection surface.
