摘要

The invention relates to a binocular optical device, of the spectacles, with a resolution and / or the field of vision, increased. & br / & this device is particularly applicable to the construction of the night vision goggles, making it possible to superimpose on the visible image an infrared image intensified, such spectacles which can be carried, for example, by a pilot of an aircraft or helicopter and making it possible to observe the scene of day and night. & br / the device comprises, for each eye of the pilot, a target (1 l) of the optical axis is given (y1 1, y1 2), which receives the infrared light. The optical axes are at an angle such that, during the observation of a scene at infinity, the two fields of vision (31, 32) are secants.
