摘要： The present invention relates to projection systems for displaying visual information in a variety of applications in order to reduce the projection area, the weight and the dimensions thereof. In one embodiment, the projection system for producing an external surface projection on a visualization screen comprises a flat and thin visualization screen for carrying out projection on both sides. Images can be watched on the left side and on the right side of this screen. From the surface of the screen and on the left and right sides thereof, projectors are provided for projecting images simultaneously on both sides of the screen. Light diffusers are provided on both sides of the screen. The projections are converted through the optics of the projectors so as to form reduced-divergence projection beams which are entirely captured by the light diffusers and which are diverted and diffused at wide angles of image observation ranges.

摘要： As an imaging prevention method for interfering unauthorized imaging of a number of visual images projected on a screen, there is employed a method for projecting infrared light to a viewer/audience direction from at least one or more infrared light projector devices disposed at a rear side of the screen. According to the method, an amount of infrared light is directly incident into an imaging apparatus whereby increasing the prevention effect causes more infrared light to be directly incident into the imaging apparatus of a person conducting the unauthorized act.

摘要： Micro-electromechanical display device (“MDD”)-based multimedia projectors (90, 120) of this invention employ an arc lamp (32), a color modulator (42), and anamorphic illumination systems (94, 121) for optimally illuminating a MDD (50, 76) to improve projected image brightness. MDDs employ off-axis illumination wherein incident and reflected light bundles are angularly separated about a hinge axis (78, 110) and the MDD is illuminated by the anamorphic illumination systems of this invention having a slow f/# parallel to the hinge axis and a faster f/# perpendicular to the hinge axis. The resulting anamorphic light bundles (86, 88, 112, 114) illuminate and reflect more light into and off the MDD and through a fast f/# projection lens.

摘要： A method adapts an output image to a shape of a display surface. First, a structured pattern is projected onto the display surface by a projector. An input image of the structured pattern is acquired by a camera in a fixed physical relationship to the projector. From the input image, a mesh of the structured pattern is determined in a coordinate frame of the projector. Coordinates of a texture are determined in the coordinate frame of the projector. The coordinates of the texture are updated according to the display region. The texture then mapped to the mesh, and the textured mesh is rendered on the display surface.

摘要： A color-separating and -recombining optical system includes a cubic- or square column-like first to fourth polarization beam splitters having polarization-splitting planes intersecting each other and wavelength-selective polarizing converters for rotating the plane of polarization of a specific-color light component by 90 degrees. One of the converters is placed at a light-incident side of the first splitter and another is placed at a light-emitting side of the fourth splitter. The first and fourth splitters are provided at light-incident and light-emitting sides, respectively, of the optical system. The first and fourth splitters are arranged diagonally opposing each other. The remaining converters are placed between at least two inner facing planes of the first to fourth splitters. At least the remaining converters and three of the first to fourth splitters are joined to form an optical joint component with a gap between the component and the remaining one splitter.

The PBS contains at least one prism having at least one major surface and having a refractive index of at least about 1.6 and a birefringent film disposed on the major surface of the prism. The birefringent film is a multi-layer film having layers of at least a first material and a second material. After uniaxial stretching, the film exhibits a refractive index difference of less than about 0.15 units in the stretched direction.
