  • Patent number: 8306378
    Abstract: Optical pulse compensator having a chirp unit including a normal dispersion fiber that provides a positive chirp to an input pulse and having a dispersion compensator including an anomalous fiber is provided. The nonlinear coefficient and the absolute value of the second-order group-velocity dispersion of the anomalous fiber that forms the dispersion compensator is set such that a soliton order becomes one or more, and the fiber length of the anomalous dispersion fiber is made to be equal to or smaller than a length required for optical soliton formation.

  • Publication number: 20120063762
    Abstract: A focus calibration apparatus allows fine adjustments to be made to the focal distance between a camera lens and sensor, in particular to take into account small changes in the mechanical tolerances such as when changing lenses. The calibration apparatus has a simple mechanism, like a focus ring, that a user can easily manipulate to simplify and speed the lens calibration process.

  • Patent number: 7330649
    Abstract: A security camera has an adjustable turret that holds a lens assembly which can be aimed in various directions. The camera also has a compact housing which, in combination with the adjustable directionality of the turret, enables universal mounting to various structures and positions in an aircraft cabin. The camera operates in light and dark conditions, as the lens assembly is configured to focus visible and infrared light wavelengths onto a fixed focal plane. In an embodiment, the camera includes an infrared illumination source to illuminate a field of view during dark conditions. The lens assembly includes a rigid barrel with a pinhole aperture through which light enters a series of lens elements. An optical sensor is mounted to an opposite end of the barrel at the fixed focal plane. The sensor is rotatably adjustable to yield a correct image orientation depending on the turret position.

  • Patent number: 6160583
    Abstract: A rectilinear barrel of a camera supporting a lens group in a manner that the lens group is movable along a rectilinear slot in the direction of its optical axis, a cam ring which has on its circumference a rib with a cutout portion and which rotates to drive the lens group in the direction of the optical axis, a threaded driving shaft for moving the rectilinear barrel between an imaging position and a retracted position, a zoom gear for rotating the cam ring when the rectilinear barrel is at the imaging position, and a locking tab for allowing the rectilinear barrel to move by means of the threaded driving shaft by aligning itself with the cutout portion and for locking the movement of the cam ring, and thus, the rectilinear barrel by aligning itself with the rib.

  • Patent number: 6026244
    Abstract: A focus adjustment mechanism upon assembly of an AF compact camera includes a shutter having a focusing lens frame which is screw-engaged therein, and a ring-shaped connecting member with an arm to be engaged with an AF driving lever of the shutter and to be fixed to the lens frame. The lens frame is provided with a cylindrical engagement surface to which the ring-shaped connecting member is engaged from the front end thereof and a plurality of engaging portions to be engaged with an adjuster for rotation of the lens frame. The adjuster comprises a plurality of corresponding engaging portions to rotate the lens frame.

  • Patent number: 5613168
    Abstract: A position adjusting apparatus for adjusting a position of a lens frame of a camera, which holds a focusing lens group, in an optical axis direction. This apparatus includes a lens frame supporting member which is rotatable relative to the lens frame, a guide which moves the lens frame in the optical axis direction during the rotational adjustment of the lens frame, and a friction mechanism which normally prevents the lens frame and the lens frame supporting member from rotating relative to each other due to a frictional force, and which permits the lens frame and the lens frame supporting member to rotate relative to each other against the frictional force when a predetermined adjusting force is applied thereto.
