An alignment mechanism uses two adjustment plates. A first adjustment plate is pivotal about a first adjustment axis and a second adjustment plate is rotatable about a second adjustment axis. The first and second adjustment axes are perpendicular to one another. The first plate has a front portion through which the first adjustment axis passes and a rear portion having a first alignment surface and a tension spring secured to the rear portion opposite the first alignment surface. The second adjustment plate has a front portion and a rear portion having a second alignment surface and a tension spring secured between the second alignment surface and the rear portion of the first adjustment plate.

A method for geolocating an image sensor having an LoS and installed on board an aircraft. The geographical position of the sensor and the orientation of its LoS being approximate, it comprises: a step of creating an opportune landmark comprising the following substeps: an operator locating, on a screen for displaying acquired images, a stationary element on the ground, the axis of a telemeter being indicated in these images by means of a reticle the direction of which represents the LoS; the operator moving the LoS in order to place the reticle on this stationary element; tracking of this stationary element; estimating the approximate geographical position of this stationary element; searching in a terrain DB for the location corresponding to a zone centered on the stationary element; displaying an image of the terrain of this location, the operator locating the stationary element; and the operator pointing to this stationary element in the displayed terrain image, the geographical coordinates pointed to being retrieved from the terrain DB, this stationary element becoming an opportune landmark; and the sensor moving relative to the landmark, a step of accurately locating the sensor, from the geographical coordinates of this landmark and using a Kalman filter supplied with a plurality of measurements of the distance between the sensor and the landmark and with a plurality of measurements of the orientation of the LoS of the sensor toward the landmark, there being one orientation measurement for each telemetry measurement, simultaneously allowing the orientation of the LoS to be accurately estimated.

Techniques are disclosed for automatically bore-sighting a laser-based optical device to a weapon or other apparatus to which the optical device may be mounted (or otherwise coupled). According to certain embodiments of the invention, a reflective element such as a retro-reflector can be located on a target, and the apparatus is sighted (or otherwise oriented) to the target. While the apparatus is thus sighted, a processing unit (or other control unit) of the laser-based optical device can manipulate a laser-steering assembly to scan the field of view of a camera of the laser-based optical device with a laser to determine where, in the field of view, the reflective element is located and how the laser-steering assembly is oriented. Hill-climbing and/or other peak-detection techniques can be used to make either or both of these determinations.

The invention relates to a sighting device having an optical reversing system (12) and a target mark as well as a ballistics computer for computing data that is relevant in terms of ballistics, the reversing system (12) being adjustable mechanically and the target mark being adjustable electronically and at least one adjusting device (13) being provided for adjusting the reversing system (12) and the target mark.

A method of adding digital functionality to a scope. A scope reticle from the scope is aligned with a virtual reticle from a digital overlay of an electronic display device coupled to the scope. The scope reticle is present in a first coordinate space of the scope image and the virtual reticle is present in a second coordinate space. The alignment of the reticles maps the first coordinate space to the second coordinate space. The coordinate spaces are then locked and the virtual reticle is made invisible, switching from a configure mode to an operate mode. Digital functionality can then be provided to the scope via the digital overlay. This may include an aiming indicator which works with the scope reticle.
