  • Publication number: 20140320852
    Abstract: A light beam is applied to a front surface of an optical depolarizer. The depolarizer rotates the polarization of light received on different surface positions by different amounts, so that the average incoming polarization is scrambled. The depolarizer has a first and second body that transmit first and second polarization components of the beam with mutually different speeds of light. Each body has two wedge shaped parts of variable thickness, corresponding wedge shaped parts in the two bodies providing light paths of substantially position independent lengths, but with variable rotation of polarization. The wedge shape parts of the front body form a concave input surface for the incoming beam. This prevents cross-over of light between the different wedge shaped parts.

  • Patent number: 8873162
    Abstract: An optical system for imaging an object on an image acquisition unit has a variable focal length for zooming. The optical system has precisely three lens units from the object in the direction of an image acquisition unit, namely a first lens unit, a second lens unit, and a third lens unit. The second lens unit and the third lens unit are movably situated along an optical axis of the optical system for a change of the focal length. The first lens unit includes a first lens group and a second lens group. The first lens group of the first lens unit is fixedly situated on the optical axis of the optical system. The second lens group of the first lens unit is movably situated along the optical axis of the optical system for focusing. The second lens group includes at least two lenses.

  • Publication number: 20140300959
    Abstract: A catadioptric telescope is a modified version of a conventional Maksutov-Cassegrain optical telescope. In accordance with the invention, the reflecting surfaces of the primary mirror and the secondary spot mirror are on the second surfaces of the primary mirror and correcting lens, respectively. In further accordance with the invention, two of these telescopes can be joined together to form a binocular telescope array. The array can be easily customized to suit different remote sensing/satellite applications.

  • Patent number: 8848290
    Abstract: Thermal wake proximate to an optical element of a telescope may be reduced. Signal(s) related to respective temperatures of support struts supporting the optical element may be generated. The respective temperatures of the support struts may be determined based on the signal(s). Individual support struts may be heated based on the respective temperatures of the support struts. Heating a given support strut may cause the given support strut to thermally expand. Individual support struts may be at least partially enclosed with corresponding shrouds. Airspaces may be disposed between individual support struts and the corresponding shrouds. Heat emitted in the airspaces by the support struts may be ejected away from the optical element to prevent a thermal wake from reaching a volume proximate to the optical element.

  • Patent number: 8848287
    Abstract: An adjustment tower for telescopic sights includes a first adjustment device and a second adjustment device, which are capable of rotating independently of one another relative to a base. The first adjustment device can be rotated in an adjustment position and has a secured position in which it is secured against rotation. The first adjustment device is also axially movable relative to the base to a limited extent such that in the adjustment position, the adjustment device projects further out of the second adjustment device than in the secured position. The tower further includes a stored-energy device that exerts an axial force on the first adjustment device from the secured position in the direction of the adjustment position.

  • Patent number: 8830576
    Abstract: A viewing device synchronizer includes a viewing mechanism for viewing an object and a linking mechanism for linking a plurality of viewing mechanisms so that each is capable of viewing the object simultaneously. A movement mechanism moves a single viewing mechanism in any direction in order to view an object. A control mechanism moves any of the plurality of viewing mechanisms if the single viewing mechanism is moved. A directional pointing mechanism controls one or a plurality of the viewing mechanisms. A communication mechanism sends directional information for controlling the operation of the plurality of viewing mechanism from a single viewing mechanism.
