An apparatus (10) comprises an optical filter (12), which resolves electromagnetic radiation into a sequence of resolved polarization components, an imaging device (14), having a storage device (16), and a driver (18). The imaging device (14) receives the sequence of resolved polarization components from the optical filter (12) and stores them in the storage device (16). The driver (18), which receives the video synchronization signal, produces a filter synchronization signal which is provided to the optical filter (12) to cause the optical filter (12) to produce the sequence of resolved polarization components so the optical filter (12) is in synchronization with the imaging device (14). This apparatus (10) is used to view the polarization properties of a scene.

Un appareil (10) comprend un filtre optique (12) qui résout un rayonnement électromagnétique en une séquence de composantes de polarisation distinctes, un dispositif de prise de vue (14) pourvu d'un dispositif d'enregistrement (16) et un circuit de commande (18). Le dispositif de prise de vue (14) reçoit la séquence de composantes de polarisation distinctes provenant du filtre optique (12) et les enregistre dans le dispositif d'enregistrement (16). Le circuit de commande (18), qui reçoit le signal de synchronisation vidéo, produit un signal de synchronisation de filtre qui est fourni au filtre optique (12) de façon que celui-ci produise la séquence de composantes de polarisation distinctes, le filtre optique (12) étant ainsi en synchronisme avec le dispositif de prise de vue (14). Cet appareil (10) est utilisé pour l'observation des caractéristiques de polarisation d'une scène.
