An optical detection system for detecting a hostile optical component without exposing the surrounding to unnecessary hazards is disclosed. The system comprises a laser unit configured to provide an adjustable laser beam along an optical path to scan for the optic component or to act as jammer by providing a target spoofing; a single aperture for the optical path; a detector configured to detect through the single aperture retroreflections of the laser beam at the optical component; and a camera for detecting through the single aperture potential candidates for the hostile optical component.

The vehicle delimits an interior space from an exterior space. The sighting device includes: a support defining an interior volume, an optronic head adapted to rotate about an axis, an optical path comprising: a collecting optical unit for collecting a portion of the surroundings of exterior space, adapted to rotate about the axis; and an optical transport system including a plurality of optical components, portion of the components being, in the interior space and the other portion being in the interior volume; a drive means driving the optronic head and the collecting optical unit so that the ratio between the angle of rotation of the head and the angle of rotation of the collecting optical unit is substantially equal to 1.

An angled mirror for an armored vehicle includes a housing having a lower look-in window or aperture, an upper look-out window or aperture and a one-part or multipart prism located in the housing. The prism has an outside view surface which remains permanently functional in strongly sandy surroundings due to a layer made of transparent ceramic that is disposed in the look-out window or aperture.

An optical device and a method for high-resolution image transfer are provided. The optical device includes an image-guiding element having a distal end and a proximal end, an inverting reflection prism having an entry face and an exit face, and a display element. The image-guiding element directs light beams into the inverting reflection prism, and after having passed therethrough they are directed to the display element, the image-guiding element being mounted for non-stop rotation over more than 360°. The light entry face and the light exit face of the image-guiding element define an angle μ to one another which is between 5° and 175°.

A periscope comprises an object window (4), a first reflector (5), a second reflector (6), a viewing window (7) and a display port for an electronic display (8). The first reflector (5) is arranged to reflect light from the object window (4) towards the second reflector (6). The second reflector (6) is selectively movable between a first position of use in which the second reflector (6) reflects light from the first reflector (5) towards the viewing window (7) and a second position of use in which the second reflector (6) reflects light from the display port towards the viewing window (7). The periscope provides a simple design that allows the user's view to be switched between an electronically generated image, such as night vision, and a purely optical image.

The invention relates to a gunner's sight having a housing, wherein the housing has at least one opening. The housing therefore is not arranged completely around the gunner's sight. At least one sight is arranged in the housing and its line of sight leads out from the opening. Also provided is at least one protection element which is at least partially transparent. The protection element can therefore constitute protection for the gunner's sight and can, nevertheless, guarantee the continued functioning of the gunner's sight as a result of the transparency of the protection element.

Systems and methods for facilitating transportation of an observer in a vehicle include providing video images of an environment of the vehicle from a plurality of cameras having partly overlapping field of views, detecting an orientation of the observer's head, combining the video images to provide a first video image of a first section of the environment of the vehicle, and presenting a second video image of a second section of the environment of the vehicle. The second section is a subset of the first section and corresponds to the detected orientation of the observer's head. The first section is a proper subset of the environment seen by the plurality of cameras. The detecting and presenting are repeated after a predetermined time-period that is short enough not to cause nausea for the observer.

The invention relates to a viewing instrument (1) for observing the surroundings and aiming at targets in the surroundings of a vehicle, in particular an armored vehicle, comprising an eyepiece unit (2) and an objective unit (3) and comprising an optical waveguide bundle (4), which connects the objective unit (3) and the eyepiece unit (2) to each other, wherein the optical waveguide bundle (4) transmits an image of the surroundings, which is focused by the optical unit of the objective unit (3) onto the objective-side end of the optical waveguide bundle (4), to the eyepiece unit (2), wherein a reticle (6) is arranged in an intermediate image plane, in which the optical unit (5) of the eyepiece unit (2) focuses the transmitted image of the surroundings as an intermediate image, and is rotatable about the optical axis (7) relative to the intermediate image.

An optical device and a method for high-resolution image transfer are provided. The optical device includes an image-guiding element having a distal end and a proximal end, an inverting reflection prism having an entry face and an exit face, and a display element. The image-guiding element directs light beams into the inverting reflection prism, and after having passed therethrough they are directed to the display element, the image-guiding element being mounted for non-stop rotation over more than 360. The light entry face and the light exit face of the image-guiding element define an angle to one another which is between 5 and 175.

The invention relates to an optronic system for a platform, the optronic system comprising: a support that can be rotated about a first axis, the support defining an space; an optronic head for observing part of the surroundings of the platform, the optronic head being mounted such that it rotates about a second axis, the second axis being perpendicular to the first axis, a hemispherical viewing device comprising a sensor with an optical system having an at least hemispherical field, the sensor being able to detect images of part of the surroundings of the platform, and a calculator for processing the images that the sensor detects, the calculator being in the inside space and the sensor being secured to the support.
