Night or day vision combat goggles, for protection against optical aggression and restitution of a small information image in the day or a wide-angle night-vision image at nighttime, comprise an interferometric filter element
Night or day vision goggles comprise an element (1) to be positioned in front of the eye of an infantryman. The element is translucent to at least a visible wavelength band. The goggles also comprise means (2, 3) for projecting images onto the surface of the elements so that they can be directly viewed by the eye. The optical element is a filter comprised of interferometric layers and the wavelength of the light emitted by the imaging means is centered on the wavelength or wavelengths filtered out by the filter.
