Abstract: The device has a stabilization mirror that is angularly steerable about two mutually orthogonal axes, and an optical system for splitting an incoming light beam into at least two channels corresponding to different wavelengths. The stabilization mirror is steerable about a first axis (L) on internal equipment that is itself steerable about a second axis (I) orthogonal to the first and intersecting in an assembly that is steerable on a support about a third axis (C). A servo-control system has a gyroscopic sensor tied to the mirror and controlling steering motors. The system further includes, upstream from the stabilization mirror, and on the path of an incoming beam, a purely catoptric optical system that is stabilized, giving the inlet beam a size on the mirror that is smaller than the size of the inlet pupil of the system.

Abstract: An optical sighting and aiming apparatus has a first channel having a disy unit provided with deviation measurement means; a second channel having a sighting member and a light deviator for angularly deviating the optical axis of the sighting member with respect to a reference direction harmonized with the center of the vision field of the display unit; and an aiming mirror inserted in a light path common to the two channels, at a location between the portions of the two channels which are separate and a multichannel collimator for adjusting the angular direction of both channels with respect to a scene being observed. The second or aiming channel further comprises a separator for separating a light beam from the multichannel collimator into a beam directed toward the sighting member and a beam directed toward a zeroing detector harmonized with the sighting member.

Abstract: A polychromatic mutual alignment device is suitable for use in an aiming apparatus having a laser delivering a parallel light beam and a plurality of light receivers to be harmonized with the laser. The device comprises an optical mixer having at least two source-forming holes each receiving light delivered in a respective one of a plurality of spectral ranges for which alignment 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 mixer output beam; and a parabolic mirror having an axis and placed so as to receive the output beam at an angle with respect to said the axis, the mixer and the mirror being constructed so that all the source-forming holes are at the focal point of the mirror.

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.
