  • Patent number: 9676500
    Abstract: A method of solar occultation, and in particular solar coronagraphy, employing a spacecraft 200 is disclosed. The spacecraft is controlled to achieve a position within a target zone relative to a celestial body, such as the Moon, such that the celestial body occults the Sun, allowing observations of the Sun or the space around the Sun, and in particular the Sun's corona, to be made from the spacecraft. The spacecraft has an orbit 40 around the Earth in a plane S, which like the Moon's orbit 20 in plane M, is inclined relative to the ecliptic plane E. Once inside the target zone, the spacecraft's orbit is controlled such that it remains in the target zone for longer than it would otherwise. This is achieved through the orbit within the target zone being at least partly non-Keplerian, when the orbit is under the influence of spacecraft translational thrust for example.

The second lens array includes a plurality of second lenses. The optical axes of the second lenses overlap with the optical axes of the first lenses. Each first lens and second lens with overlapping optical axes form a unit optical system. Each unit optical system is an erecting equal-magnification optical system. Each unit optical system is substantially telecentric on at least the object side. The imaging position, by each first lens, of an object is positioned between the first lens array and the second lens array.

  • Patent number: 8721089
    Abstract: The image projection apparatus is disclosed to which plural interchangeable optical units are selectively attachable. The apparatus includes a shift mechanism moving an attached optical unit, which is one of the plural interchangeable optical units that is attached to the apparatus, with respect to a light modulation element in a direction orthogonal to an optical axis, an actuator driving the shift mechanism, and a controller controlling drive of the actuator using a control parameter for moving the attached optical unit by a specific movement amount via the shift mechanism. The controller acquires information on at least one of a weight and an optical characteristic of the attached optical unit from a memory provided in one of the apparatus and the attached optical unit, and to change the control parameter using the acquired information.

  • Patent number: 8692867
    Abstract: An image acquisition device having a wide field of view includes a lens and image sensor configured to capture an original wide field of view (WFoV) image with a field of view of more than 90°. The device has an object detection engine that includes one or more cascades of object classifiers, e.g., face classifiers. A WFoV correction engine may apply rectilinear and/or cylindrical projections to pixels of the WFoV image, and/or non-linear, rectilinear and/or cylindrical lens elements or lens portions serve to prevent and/or correct distortion within the original WFoV image. One or more objects located within the original and/or distortion-corrected WFoV image is/are detectable by the object detection engine upon application of the one or more cascades of object classifiers.

  • Patent number: 8525199
    Abstract: In a solid-state image capturing device having the locations of photodiodes in each pixel unit to be different according to a sequence, the light receiving sensitivity and the luminance shading characteristic are improved. A circumferential portion of a microlens 12 which is arranged above a corresponding photodiode 11 is formed so as to overlap an adjacent microlens 12 thereto, and the locations of microlenses 12 in each pixel unit are different according to a sequence. Light of an image that is incident upon each of the microlenses 12 is incident upon approximately the same portion (e.g., central portion) of each of the respective photodiodes 11.

  • Patent number: 8508845
    Abstract: Producing a scaled multiple parallax compound lens is accomplished by providing an insect eye having multiple ommatidia and creating a polymer mold of the insect eye. A casting is then created from the polymer mold with an expandable polymer which is then linearly expanded to provide a form for creating a second polymer mold. A second casting is then created from the second polymer mold. Duplication of the process can be accomplished for further scaling up of the compound lens with the final casting created using a durable polymer having appropriate optical properties for the lens.
