Monocular or binocular viewing systems worn on the head of a user are provided. Each monocular assembly comprises a display and an optical assembly including an optical relay and a partially transparent optical combiner taking the form of an inclined curved plate, each optical assembly arranged to form a second image at infinity from a first image displayed by a display. The optics are to be crossed such that, in the case of a binocular system, if one optical combiner is placed in front of the right eye of the user, the optical relay and the corresponding display are placed in a forehead-facing position above the left eye of the user and under the optical combiner located on the left-hand side. This arrangement is obtained by judiciously choosing the geometric parameters of the various optical elements, their curvatures and the form of their surfaces.

A modular night visualization system with fused optical sensors comprises a light-intensifying base module and an image-sensing auxiliary module. The connections according to the system provide a modular system in which the auxiliary module is easily interchangeable with a different auxiliary module. Thus, a compact and modular visualization system that is operationally easier to use is provided. The system may be a night-vision field-glass for a foot soldier enabling fusion of sensors. Any other application for a vision field-glass with fused sensors is possible.

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.

A system for the reduction of a laser equivalent surface area and for the optical protection of an optical device including a first polarizer and a first multiple wavelength quarter-wave plate placed in series in the path of a multiple wavelength light beam between the polarizer and the optical device. This system brings into play polarized light, and associates a liquid crystal shutter with it, providing for protection against optical aggression. The entire unit may take the form of a detachable optical attachment.
