Sighting device for vehicle and associated vehicle

A sighting device for a vehicle, the vehicle including a wall delimiting an interior space from an exterior space, the sighting device including:

• a support mounted rotating relative to the wall around a first axis, the support defining an interior volume, the support including two lateral arms and a base, the two lateral arms and the base being arranged to form a substantially U-shaped part,
• an optronic head for indirect observation of a first part of the environment of the exterior space, the optronic head being mounted rotating on the support around a second axis, the second axis being perpendicular to the first axis,
• a direct optical path for observation of a second part of the environment of the exterior space, the optical path comprising:
• a collecting optical unit adapted to collect an image of the second part of the environment of the exterior space, the collecting optical unit rotating around the second axis, and
• an optical transport system adapted to transport the image collected by the collecting optical unit to at least one predefined location in the interior space, the optical transport system including a plurality of optical components, part of the optical components being in the interior space and the other part of the optical components being in the interior volume of the support, at least one of the optical components being in one of the lateral arms, and
• a drive organ driving the optronic head and the collecting optical unit so that, when the optronic head performs a rotation by a first given angle around the second axis, the collecting optical unit performs a rotation by a second given angle around the second axis, the ratio between the two angles being between 0.99 and 1.01.
