Abstract: front page image
(EN)A scanning system for scanning a field of regard (FOR) by dividing it into a plurality of fields of view (FOVs) having different spatial orientations. The system has a scanning unit (10) and a fixed optical system (12) having a line of sight (23). The scanning unit has a plurality of discrete reflective surfaces (30, 32), each having different orientations relative to the reference plane and facing in one of a corresponding plurality of directions of sight to define the FOVs. Each reflective surface has an operative state when its FOV is in optical communication with said optical system and a corresponding inoperative state, and is radially spaced from said reference axis at least in the inoperative state. A switching mechanism (20, 22, 24) is also provided for switching between the reflective surfaces (30, 32) to successively bring them into their operative state while maintaining substantially unchanged their orientation and the spatial orientation of the FOV.
(FR)L'invention concerne un système de balayage servant à balayer un champ de regard (FOR) en le divisant en une pluralité de champs de vision (FOV) possédant des orientations spatiales différentes. Le système comprend un module de balayage (10) et un système optique fixe (12) possédant une ligne de visée (23). Le module de balayage présente une pluralité de surfaces réfléchissantes discrètes (30, 32), possédant chacune des orientations différentes par rapport à un plan de référence et tournées chacune dans l'une d'une pluralité de directions de visée correspondantes de manière à définir les champs de vision. Chaque surface réfléchissante possède un état fonctionnel dans lequel son champ de vision est en communication optique avec ledit système optique, et un état non fonctionnel correspondant dans lequel elle est décalée radialement par rapport à un axe de référence. Un mécanisme de commutation (20, 22, 24) permet d'assurer la commutation successive des surfaces réfléchissantes (30, 32) dans leur état fonctionnel tout en conservant sensiblement leur orientation et l'orientation spatiale de leur champ de vision.
