  • Patent number: 10416422
    Abstract: A zoom lens forms an intermediate image at a position conjugate to a reduction side imaging plane and forms the intermediate image again on a magnification side imaging plane. The zoom lens includes a first optical system on the magnification side, and a second optical system on the reduction side. The intermediate image is formed between the magnification and reduction sides. The second optical system includes two or more movable lens groups, which move by changing spacings between the groups adjacent to each other in a direction of an optical axis during zooming, and two stationary lens groups which remain stationary with respect to the reduction side imaging plane during zooming. One stationary lens group is disposed closest to the reduction side, and has a positive refractive power. Also, a lens group closest to the magnification side in the second optical system has a positive refractive power.

  • Patent number: 10288861
    Abstract: A light sheet microscope includes an objective, an illumination optical system, a correction device, an image pickup device, a first adjustor, a second adjustor and a controller. The controller performs a first focus process and a spherical aberration correction process. The first focus process is a process in which the first adjustor is controlled on the basis of light that is from the light sheet plane and that is detected via the objective so that the light sheet plane and a focal plane become closer when a relative position between the light sheet plane and a sample has been changed. The spherical aberration correction process is a process in which the correction device is controlled so that an evaluation value of the image obtained by the image pickup device becomes greater when the first adjustor has changed the relative position between the light sheet plane and the objective.

  • 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.

  • Patent number: 8279738
    Abstract: There is provided an objective lens for information recording/reproducing for three types of optical discs, which includes a first area contributing to converging a third light beam onto a record surface of a third optical disc. The first area includes a phase shift structure having refractive surface zones concentrically formed about a predetermined axis. The phase shift structure includes first and second step groups. The first step group is configured such that an optical path length difference ?OPD1 (nm) given by each step of the first step group to a first light beam satisfies a condition: 2N1+1.10<|?OPD1/?1|<2N1+1.40, where N1 is an integer or zero, and the second step group is configured such that an optical path length difference ?OPD2 (nm) given by each step of the second step group to the first light beam satisfies a condition: 2N2?0.10<|?OPD2/?1|<2N2+0.10, where N2 is an integer.

  • Patent number: 8188880
    Abstract: The present application discloses methods and systems for augmenting a field of view of a user. In one embodiment, a device may include a detector, a processor, and an array of visual indicators. According to an embodiment of the method, the detector may image an environment. The processor may identify within the environment imaged by the detector an object of interest. The processor may also determine a relative spatial location of the identified object of interest. Further, the array of visual indicators may be used to indicate the determined relative spatial location of the identified object of interest. In particular, a set of one or more visual indicators may be selected that has a relative spatial location in the array of visual indicators that is indicative of the relative spatial location of the identified object of interest.
