Title (EN) FILTER DEVICE FOR AN OPTICAL SENSOR
(FR) DISPOSITIF DE FILTRE POUR UN CAPTEUR OPTIQUE
(DE) FILTEREINRICHTUNG FÜR EINEN OPTISCHEN SENSOR
Abstract:
(EN) A filter device (30) for an optical sensor (10, 20), comprising: - a hologram with a defined number of holographic functions, which are embodied in such a way that optical radiation striking the filter device (30) from a defined first solid angle (40) is blocked by the filter device (30) and that optical radiation striking the filter device (30) from a defined second solid angle (FOVhori, FOVvert) is able to pass the filter device (30).
(FR) L'invention concerne un dispositif de filtre (30) pour un capteur (10, 20) optique. Le dispositif de filtre comporte : un hologramme comprenant un nombre défini de fonctions holographiques qui sont réalisées de telle manière qu'un rayon optique arrivant sur le dispositif de filtre (30) depuis un premier angle solide (40) défini est bloqué par le dispositif de filtre (30), et qu'un rayon optique arrivant sur le dispositif de filtre (30) depuis un deuxième angle solide (FOVhori, FOVvert) défini peut traverser le dispositif de filtre (30).
(DE) Filtereinrichtung (30) für einen optischen Sensor (10, 20), aufweisend: - ein Hologramm mit einer definierten Anzahl von holografischen Funktionen, die derart ausgebildet sind, dass aus einem definierten ersten Raumwinkel (40) auf die Filtereinrichtung (30) auftreffende optische Strahlung von der Filtereinrichtung (30) blockiert wird und dass aus einem definierten zweiten Raumwinkel (FOVhori, FOVvert) auf die Filtereinrichtung (30) auftreffende optische Strahlung die Filtereinrichtung (30) passieren kann.
