    Abstract: Imaging systems in which an undedicated optical component—i.e., a component that would be present in the system even in the absence of image stabilization—is configured to undergo corrective motion and/or other correction of image data, and thus to function as a stabilization component. The stabilization component may be a mirror and/or a lens, and a positioner may be provided to tilt, rotate, and/or otherwise precisely adjust the position and orientation of the stabilization component to improve image resolution, compensate for platform motions such as platform vibration, and/or improve image tracking. Because an undedicated optical component functions as the stabilization component, the stabilization occurs upstream, rather than downstream, from separation (if any) of the incoming image data into two or more beams.

    Abstract: Optical elements having components made from high refractive index materials (RI?1.6) and lamp assemblies incorporating such elements. Various optical elements, such as total internal reflection lenses, can be fabricated from materials having a higher index of refraction than materials typically used in such elements. The compact optical elements have at least one internal reflection surface that directs radiant energy (e.g., light) from a receiving end to a transmitting end. By using a high refractive index material, a lens can be fabricated that directs a greater portion of the light emitted from a source into the lens toward the transmitting end of the lens. Thus, less of the light spills out of the lens at a surface where emission is not intended, reducing the number of lossy bounces needed to direct the light in a particular direction.

  • Patent number: 8123371
    Abstract: An all-reflective optical system includes a primary mirror of ellipsoidal configuration, a secondary mirror of hyperboloidal configuration facing the primary mirror, and an eye-piece that includes: a positive-powered tertiary mirror having a majority of positive power that is expected in the eye-piece and configured to substantially collimate light rays incident thereon; and a negative-powered near-flat quaternary mirror having lesser power than the tertiary mirror and configured to receive the substantially collimated light rays from the tertiary mirror, further collimate the received light rays and reflect the further collimated light rays to an exit pupil. The primary mirror, the secondary mirror and the eye-piece thereby form an afocal optical system.

  • Publication number: 20110279913
    Abstract: An annular inclined surface is formed on an edge portion of a first plastic lens in such a manner that the inclined surface surrounds a concave surface formed in a second surface of the first plastic lens. The inclined surface reflects unwanted light reflected by the concave surface so as to prevent the unwanted light from passing through the non-shading portion of the edge portion outside the effective area of a lens portion and then being reflected on an imaging area. This can suppress ghosting and flare due to the reflection of the unwanted light on the imaging surface.

  • Patent number: 8035898
    Abstract: One embodiment of a method of calculating an optical surface comprises calculating a meridional optical line of the surface. A ray is selected that passes a known point defining an end of a part of the optical line already calculated. The optical line is extrapolated from the known point to meet the ray using a polynomial with at least one degree of freedom. The polynomial is adjusted as necessary so that the selected ray is deflected at the extrapolated optical line to a desired target point. The polynomial is added to the optical line up to the point where the selected ray is deflected. The point where the selected ray is deflected is used as the known point in a repetition of those steps.

    Abstract: According to one embodiment relates to an optical system radially downsized and corrected well for aberration and is applicable, for example, to an aberration measuring apparatus for measuring wavefront aberration of a liquid immersion projection optical system. A catadioptric system of a coaxial type is provided with a first optical system which forms a point optically conjugate with an intersecting point with the optical axis on a first plane intersecting with the optical axis, on a second plane, and a second optical system which guides light from the first optical system to a third plane.

    Abstract: A laterally emitting radiation-generating component comprising a radiation source, the optical axis of which runs perpendicular to a mounting area of the component, and comprising an optical device arranged downstream of the radiation source. The optical device includes a reflective surface shaped like a V in cross section and a refractive surface that is shaped convexly as seen externally and is arranged between the reflective surface and a bottom area facing the radiation source. The bottom area is arranged and formed in such a way that through it electromagnetic radiation from the radiation source couples into the optical device. The reflective surface is arranged and formed in such a way that a central first portion of the coupled-in radiation is deflected toward the refractive surface by the reflective surface.

  • Patent number: RE42570
    Abstract: An aspheric reduction objective has a catadioptric partial objective (L1), an intermediate image (IMI) and a refractive partial objective (L2). The catadioptric partial objective has an assembly centered to the optical axis and this assembly includes two mutually facing concave mirrors (M1, M2). The cutouts in the mirrors (B1, B2) lead to an aperture obscuration which can be held to be very small by utilizing lenses close to the mirrors and having a high negative refractive power and aspheric lens surfaces (27, 33). The position of the entry and exit pupils can be corrected with aspherical lens surfaces (12, 48, 53) in the field lens groups. The number of spherical lenses in the refractive partial objective can be reduced with aspherical lens surfaces (66, 78) arranged symmetrically to the diaphragm plane. Neighboring aspheric lens surfaces (172, 173) form additional correction possibilities.

    Abstract: A panoramic lens includes an aspherical convex surface and an aspherical concave surface. The convex surface includes a transparent portion and an internally reflective portion, and the concave surface also includes a transparent portion and an internally reflective portion. Light from a 360-degree surrounding scene enters the panoramic lens through the transparent portion of the convex surface, is reflected by the internally reflective portion of the concave surface, is reflected by the internally reflective portion of the convex surface, and exits the panoramic lens through the transparent portion of the concave surface as a narrow column of light beams. Light beams containing image data can be provided to the transparent portion of the concave surface, and those beams will follow this same optical path through the panoramic lens in reverse to project a panoramic image out from the transparent region of the convex surface.
