Abstract
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.
