摘要： A portion of a first paraboloid (30) collects and concentrates randomized light from a lamp (20) into parallel beams directed to a portion of a second paraboloid (40) which refocuses the light onto a homogenizer (60). The second paraboloid has a shape that is substantially similar to the first paraboloid reflector. The source and the target are located at the respective foci of the paraboloids such that the optical flux from the source is imaged to the target with minimal distortion in an approximately no magnification imaging system. The system may be configured to control wavelength and intensity by inserting an additional filter. In addition, a retro-reflector may be added to increase the overall flux density at homogenizer. The output is particular suitable for providing light to the light engine of projectors.

摘要： A waveguide polarization recovery system both polarizes the input light energy for use with an LCD imager and converts the polarity of unusable light energy to add to the illumination of the LCD imager. The compact polarization recovery waveguide system generally includes: (1) an input waveguide that provides non-polarized light energy into the system; (2) an output waveguide that receives polarized light energy from the system; (3) a polarized beam splitter that received the light energy from the input waveguide and transmits lights energy of a first polarization type and reflects light energy of a second polarization type, and (4) a wave plate that modifies the polarization of either the transmitted or reflected light energy. The polarization recovery system also generally includes one or more mirrors that are positioned as need to direct the transmitted and the reflected light energy to the output waveguide. The input and output waveguides may be shaped as needed by the projection system. For example, either one or both of the input and output waveguides may be tapered as needed to produce a desired image. In the waveguide polarization recovery system, the input and output waveguides are configured to have either an either a substantially parallel or a substantially perpendicular orientation. In another embodiment, the waveguide polarization recovery system further includes has one or more "gaps" of optically clear material positioned between the optical components to encourage the occurrence of total internal reflection that minimizes the loss of the optical energy by the system.

摘要： An electromagnetic radiation source (SO), such as an arc lamp, is located at a point displaced from the optical axis of a concave toroidal reflecting surface (M1). The concave primary reflector (M1) focuses the radiation from the source (SO) at an off-axis image point that is displaced from the optical axis. The use of a toroidal reflecting surface enhances the collection efficiency into a small target (T), such as an optical fiber, relative to a spherical reflecting surface by substantially reducing aberrations caused by the off-axis geometry. A second concave reflector (M2) is placed opposite to the first reflector (M1) to enhance further the total flux collected by a small target (T). In accordance with one embodiment, the present invention is directed to devices in which the square of the off-axis distance divided by the radius of curvature is equal to or less than the extent of the source of electromagnetic radiation (yo /r

摘要： A method and apparatus which can couple a high intensity point source (PS), such as from a single fiber, to a fiber bundle (B). A bundle of fibers is fed through a hole in the light post (200). A removable potting compound is applied to the tip of the bundle to hold the fibers together for polishing. The tip of the bundle is polished and then the potting compound is removed from the tip of the bundle. A window (210) is placed over a light inlet of the hole so as to seal the bundle. A point source cable (PS) introduces a point source of light to the bundle of fibers.

摘要： An optical coupling element for use in large numerical aperture collecting and condensing systems. The optical coupling element includes a lens (503) having a curved surface and a tapered light pipe (504). The curved surface reduces the angle of incidence of the light striking the input end of the optical coupling element such that the Fresnel reflection is greatly reduced. Electromagnetic radiation emitted by a source (506) is collected and focused onto a target by positioning the source of electromagnetic radiation at a first focal point of a first reflector (508a) so that the source produces rays of radiation reflected from the first reflector that converge at a second focal point (511) of the second reflector (508b). The optical coupling element is positioned so that a center (507) of the lens is substantially proximate with the second focal point of the second reflector and the curved surface (505) is between the second reflector and the center. The converging rays of radiation reflected from the second reflector pass through the curved surface of the lens and reach the center.

摘要： An illumination engine for a projection display using a tapered light pipe(718) including a reflector having first and second focal points. A source of electro-magnetic radiation disposed proximate to the first focal point of the reflector emits rays of radiation that reflect from the reflector toward the second focal point. A tapered light pipe(718) collects and transmits substantially all of the radiation converged at the second focal point(722), adjusting the numerical aperture of the radiation, but curving the surface formed by the images of the radiation. A straight light pipe(724) or a lens collects and transmits substantially all of the radiation transmitted by the tapered light pipe , flattening the surface formed by the images of the radiation. A condenser lens(707) collects and transmits all of the radiation transmitted by the contoured delay element to a polarizing beam splitter(740) and a projection system (738).
