Abstract
The field of the invention is that of weapon aiming sights having a light intensifier. To make certain firing modes safe, a weapon may be provided with a camera allowing a soldier to take aim while remaining protected. The proposed invention allows this function to be fulfilled at night. For this purpose, a night vision aiming sight with a light intensifier comprising two optical channels is fitted onto the weapon. The first optical channel provides the camera placed on the weapon with an intensified image. The second optical channel provides the firer with a directly observable intensified image. In a variant, the aiming sight also includes a display that supplies the soldier with additional information superimposed on the intensified images.
