An omnidirectional optronic system includes two axes of rotation, a carrier axis and a carried axis, that are perpendicular to each other, for an aircraft targeting pod, having an imaging channel and a laser channel, the laser channel at the point of injection at the entrance of the system and the imaging channel being concentric with the carrier axis, then split and emitted out in parallel.

Omnidirectional optronic system having two rotation axes

An optical system for laser-pointing a target through the atmosphere, with four optical channels: a passive imaging channel with an auxiliary camera linked to a coarse pointing control device; an illumination channel with a pulsed illumination source and temporal synchronization means, these channels including a first common optical coarse pointing device; an effector channel with a high-power laser source; an active imaging channel with: a high-speed camera synchronized with the illumination source by the synchronization means, and linked to a fine pointing control device; means for harmonizing the high-speed camera with the high-power laser source; the active imaging and effector channels form a pair and include a second common optical coarse pointing device, the coarse pointing devices controlled by the coarse pointing control device; a common optical fine pointing device, controlled by the fine pointing control device; and the coarse pointing control device is linked to the fine pointing control device.

Optical system and method for pointing a laser through the atmosphere

The invention relates to a method of stabilizing the images of a scene, acquired by means of an observation device of an imaging system, comprising the step of digital processing of a stream of successive images. It comprises a step of acquiring gyrometric measurements by means of at least one gyrometric sensor secured to the observation device, of using these gyrometric measurements to determine so-called approximate shifts undergone between successive images, and the image processing step comprising a sub-step of using the approximate shifts and the image stream acquired to determine so-called fine shifts undergone between successive images.
