Abstract: An apparatus for detection of optical systems in a terrain area, has at least: a laser arrangement with a laser light source, a moving mirror for scanning the terrain area and a photoelement for detection of retroreflected laser radiation from the laser light source, a scan position sensor for detection of a scanning direction, and a controller for determination of the position of an optical system to be detected, from a measurement which is carried out by means of the laser arrangement by evaluation of the intensity of retroreflected laser radiation from an optical surface of the optical system, and evaluation of the associated scanning direction detected by the scan position sensor, with the controller having an electronic interface via which information relating at least to the intensity and the elevation of the detected retroreflected laser radiation can be transmitted to at least one display apparatus.

Abstract: A method and an apparatus are used for detecting optical systems, for example a sniper within a terrain. The terrain is optically scanned by means of a movable mirror and the position of the optical system is determined from a measurement made by a laser unit and is optically displayed. The position of the optical system is directly determined from the measurement made by the laser unit by evaluating the intensity of a light beam from the laser unit, after having been reflected by an optical surface of the optical system. The position is optically reflected into the field of vision of a telescope. The apparatus comprises a laser unit having a movable mirror, a control unit for detecting the position of the optical system from a measurement made by the laser unit, and a device for optically displaying the position. The device for optically displaying is a telescope, and means are provided for optically reflecting the position of the optical system into the field of vision of the telescope.

Abstract: An illumination apparatus for a telescopic sight has a lamp, in particular for a reticle of the telescopic sight. The apparatus comprises a control circuit for supplying the lamp, and an adjustment knob cooperating with the control unit for adjusting the brightness of the lamp. Incremental markings are associated with the adjustment knob. The control unit is provided with first means for scanning the incremental markings when the adjustment knob is operated, second means for generating incremental signals, and third means for generating from the incremental signals a signal for controlling the brightness of the lamp.

Abstract: The invention relates to a high-precision digital image stabilization of an image recording with a CCD sensor utilized in a moving or flying carrier. For the digital image stabilization, the movements of the carrier are detected with the aid of an inertial sensor and stored. Then, a correction of the image data is carried out based on the detected movements.

Abstract: An optical device for use under significantly varying ambient pressure is provided comprising a housing, a transparent element, a first sealing device and a protection apparatus. The housing has an interior part, an environment outside the housing and a recess in a first region. The transparent element is arranged in the first region in a region of the recess. The first sealing device is sealing a first sealing gap between the transparent element and the housing. Furthermore, the first sealing device is sealing the interior part of the housing relative to the environment of the housing up to a first pressure level. The protection apparatus is arranged outside the housing and is displaceable from a first functional position into a second functional position.
