Abstract: A camcorder mounted on a binocular includes a periscope that receives incident light on the effective line-of-sight of the binocular and reflects the light onto the line-of-sight of the camcorder into image processing elements of the camcorder, the camcorder being operable in telephoto mode and the binocular having a wide angle field of view, whereby the binocular serves as the target acquisition and maintenance of centering means for the camcorder, thereby enabling easiest acquisition of a target and enabling distant subjects of particular interest to be recorded in largest image without loss of sight of the target when the camcorder is operated in telephoto mode.

Abstract: An optical system provides a lens cell having a generally cylindrical lens cell body and an optical lens system therein. The lens cell body has a lens cell central longitudinal axis and a lens cell optical axis, eccentrically offset from the lens cell central longitudinal axis. A sleeve has a generally cylindrical sleeve body, an outer surface with a first longitudinal axis, and an inner surface with a second longitudinal axis, eccentrically offset from the first longitudinal axis. The lens cell is inserted into the sleeve. A housing has a generally cylindrical body into which the sleeve is at least partially inserted. The lens cell and the sleeve are rotated relative to each other and to the housing such that the lens cell optical axis is aligned in a desired location. After the lens cell optical axis is aligned in the desired location, the lens cell is fixedly connected to the sleeve and the sleeve is connected to the housing to prevent rotation of the sleeve relative to the housing.

Abstract: A vision aid in the form of telescopic spectacles has two lens systems, which each comprise at least one objective lens (70) and one eyepiece (71). An autofocussing element which changes the focal length of the lens systems for sharp focussing thereof according to the distance of the telescopic spectacle from the object is assigned to the lens systems. Furthermore, an element for changing the magnification factor by changing the focal length of the lens systems (“zoom”) and finally an element for matching the parallax between the lens systems of the vision aid to the focal length which has been set according to the distance of the telescopic spectacles from the object are assigned to the lens systems. The parallax is adapted using adjustable optical elements (11) which are located in the beam path of the lens systems, with which elements the angle (13) between the beam paths (14) running from the lens systems (1) to the object can be changed.

Abstract: A camera system has a rotary mirror type camera assembly including a camera, a mirror for camera arranged in front of the camera, and a mirror rotating mechanism driving the mirror for the camera, a rotary mirror type display apparatus including a monitor displaying an image picked up by the camera, a mirror for monitor arranged in front of the monitor, a finder permitting viewing of the image displayed on the monitor via the mirror for monitor, and a casing rotatable together with the mirror for monitor. The mirror for camera is rotated according to rotation of the casing and the mirror for monitor being fixed to the casing. When the casing is rotated, the mirror for monitor is rotated in display direction of the monitor in front of the monitor.

Abstract: A support for adjusting the line of sight of a night vision monocular. The support has a shelf that is supported relative to a user's eyes and a flange that is coupled to the shelf and rotatable relative to the shelf. The support also has a shaft supporting the monocular. The shaft is coupled to the flange for tilting the monocular relative to the shelf concurrently with a rotation of the flange. The support also has a tilt control means coupled to the flange for applying an axial force to the flange to control the rotation of the flange and the tilting of the monocular.

Abstract: An optical device comprises a lens barrel and a casing. The casing has two casing sections that are movable relative to each other. A distribution cable is provided in the casing, and extends between the casing sections. The distribution cable is loosely wound around the lens barrel, whereby a movement of the distribution cable, caused by a relative movement of the casing sections, is absorbed by the loosely wound portion of the distribution cable.

Abstract: Proposed are binoculars having a very small volume when not in use. The binoculars are provided with a housing having two end walls and a central part connecting the end walls, wherein at least one lens is arranged in each end wall, such that the two lenses are essentially located on a joint optical axis when in the working position. The end walls are attached to the central part in such a way that they can be pivoted out of the working position. The central part can then be folded up when the end walls are pivoted out of the working position.

Abstract: An Eyepiece-support arm assembly device on an aircraft. The device comprises flanges formed on the eyepiece-support arm and on a support attached to the aircraft, along with a retention belt (32) liable to be set to a locking status, wherein the arm is immobilised in relation to the support, a setting status, wherein the arm can be moved between a position for use and a retracted position, and a disassembly status allowing the assembly and disassembly of the eyepiece-support arm, without modifying the setting. The status is changed by operating levers (44, 46).

Abstract: Headgear apparatus allows a viewer to see objects in a periscopic direction and a normal direction simultaneously. A periscope is mounted to a headpiece that is easily supported by the viewers head. The periscope has movable mirrors and an extending periscope section to allow the viewer to change the angle of the periscopic view relative to a plane containing a normal line of sight and the peripheral distance of the periscopic view, respectively. The apparatus further has a sectional periscope, whereby sections containing the reflective elements of the periscope can be rotated relative to each other and change the periscopic view in the plane of the forward line of sight. The head gear apparatus is adapted to a mask or an underwater mask that allows a viewer to see objects in a periscopic direction and a forward direction in diverse environments such as under water.

Abstract: A Newtonian binocular telescope (20), which is readily adaptable to popular telescope mounts, such as the Dobsonian mount (76), and which includes two primary mirrors (42a, 42b), and two secondary mirrors (32a, 32b), in a single tube (21) of either solid wall or open frame construction. The single tube (21) allows central secondary optical axes (34a, 34b) to be disposed in laterally and longitudinally separate parallel relation to one another so as to form a comfortable interocular axis (36) between them. Both telescopes' oculars (50a, 50b) are conveniently disposed adjacent an ocular wall (22) on a side of tube (21) nearest one of the telescopes. The viewer is provided easy access (91a, 91b and 92a, 92b) to primary alignment means (87a, 87b), which may be used to merge images between telescopes.

Abstract: The self-retracting sighting device for an onboard optoelectronic localization and identification system has an elongated shape such that its rotation axis in elevation, beneath the fuselage of the carrier, is off-centered with respect to the input pupil. For the bottom line of sight, the device protrudes out of the fuselage to a major extent but, when the elevation angle increases, the device self-retracts beneath the fuselage, the top lines of sight being obtained without hindrance to the pilot's visibility. By additional rotation about the elevation axis, the input pupil is completely retracted beneath the fuselage, that part of the sighting device that protrudes out of the fuselage being then at its minimum and having an aerodynamic shape. The device can be applied notably to carriers in which the pilot's visibility is essential, for example during the stages of touchdown on aircraft carriers.
