  • Patent number: 4922801
    Abstract: A fire control system for a weapon having an operator-aimed barrel compri a sighting piece carried by the barrel and having a reticle adjustable in position with respect to the bore axis of the barrel. A camera fast with the barrel has a field coaxial with the bore axis. The apparent movement of the target in the field of the camera is measured as well as the angular movements of the barrel by the operator. The position to be given to the reticle is computed from variations of the aiming direction of the barrel and from the apparent movement and the position of the reticle is consequently adjusted. The reticle may consist of a LCD.

  • Patent number: 4811061
    Abstract: A polychromatic mutual alignment device for an aiming apparatus includes an optical mixer having at least two holes each receiving light emitted in one of different spectral ranges for which boresighting is to be achieved and a plate which is transparent in a wave length range and reflective in another wave range for combining the two light beams into a common block output beam. A parabola mirror receives the output beam at an angle with respect to its axis. The mixer and the mirror being so located that all source-forming holes are at the focus of the mirror.
