A stereoscopic imaging arrangement comprises a) an optical device (1) having an objective (2) and further lens means (3) located remotely from but in the optical path of the objective and b) a stereoscopic imaging device (4) arranged to receive light from said further lens means and form an image on a photosensitive image plane (7) the stereoscopic imaging device having shutter means (5) arranged to selectively occlude light exiting from left and right regions of said further lens means to form right and left images on said image plane and having means for combining said right and left images to form a stereoscopic representation of the field of view of said objective. The image may be displayed on a monitor (9) and viewed stereoscopically with switching spectacles (10)

Un dispositif d'imagerie stéréoscopique comprend: a) un système (1) optique doté d'un objectif (2) et d'autres lentilles (3) placées à distance de cet objectif mais sur son trajet optique et b) un système (4) d'imagerie stéréoscopique conçu pour recevoir la lumière de ces autres lentilles et former une image sur un plan (7) d'image photosensible. Ce dispositif d'imagerie stéréoscopique comporte un obturateur (5) disposé de façon à bloquer sélectivement la lumière provenant des zones gauches et droites de ces autres lentilles pour former des images droite et gauche sur ce plan d'image. Il comporte aussi un élément permettant de combiner ces images gauche et droite pour former une représentation stéréoscopique de l'angle de champ de cet objectif. Cet image peut s'afficher sur un écran (9) de contrôle et être vue en stéréoscopie avec des lunettes (10) à polarisation croisée.
