摘要： A polarizer optical device for receiving and transmitting light is provided. The polarizer optical device includes a light separating section for separating the light into two polarization components which are othogonal with respect to one another. Further, the optical device is provided with a polarization rotating section for rotating the two polarization components so that a phase difference between the two polarization components othogonal to each other is 1/2.lambda.. Finally, a light combining section is provided for combining the light into a outputted light beam. The light combining section may be formed with a combination of birefringent prisms and isotropic mediums interfacing one another. In these configurations, the refractive index of each prism or medium is selected so that an angle formed with two unparallel incident lights differs from an angle formed with two output or transmitted lights. The two unparallel incident lights and the two output lights travel on a plane surface which is vertical with respect to the interface surface between the two prisms.

摘要： A polarization luminaire is disclosed having a light source, a system of the optical integrator, a polarized light splitting device for splitting a light emitted from the light source into two kinds of polarized lights whose polarization directions are perpendicular to each other and whose traveling directions are apart from each other by an angle of less than 90 degrees, and a polarization conversion device for causing the two kinds of polarized lights to have the same polarization direction. The polarized light splitting device is placed on one of the entrance side and the outputting side of the first lens plate of the system of the optical integrator or is placed within the second lens plate. A prism beam splitter having a polarized light splitting film constituted by a thermally stable dielectric multi-layer film is suitable for the polarized light splitting device. Most of the polarized lights can be utilized by causing the polarized lights to have the same polarization direction. Further, the polarized lights, which have uniform brightness, can be emitted. Consequently, the polarization luminaire is suited to be a luminaire for use in a projection display that has liquid crystal light valves.

摘要： A polarization luminaire of the present invention has a light source, an optical integrator, a polarized light splitting means and a polarization conversion means. The polarized light splitting means splits a light emitted from the light source into two kinds of polarized lights. The polarization directions of the two kinds of polarized lights are perpendicular to each other and travel in directions separated by an angle of less than 90 degrees. The polarization conversion means modifies the two kinds of polarized lights to have the same polarization direction. The polarized light splitting means is placed on the entrance side or the outputting side of a first lens plate of the optical integrator, or is placed within a second lens plate. A prism beam splitter having a polarized light splitting film that includes a thermally stable dielectric multi-layer film may be used as the polarized light splitting means. The present invention utilizes most of the polarized lights by causing the polarized lights to have the same polarization direction. Further, uniform brightness is emitted. Consequently, the polarization luminaire of the present invention is suited for use in a projection display.
