Title (EN) DUAL-MODE IMAGING RECEIVER
(FR) RÉCEPTEUR D'IMAGERIE BIMODALE
Abstract:
(EN) A dual-mode imaging receiver (DMIR) can acquire and maintain SOA free-space optical communication (FSOC) links without a precision mechanical gimbal. Unlike other FSOC technologies, a DMIR can operate without precise spatial alignment and calibration of the transmitter's or receiver's spatial encoders (precision pointing) in static (fixed point to point) geometries. Instead, a DMIR uses electronic receive beam selection to acquire and track transmitters with coarse mechanical pointing and a single aperture. And because the DMIR can operate with just one aperture, it does not need a beacon at the transmitter since it does not transition from a wide field-of-view acquisition aperture to a narrow field-of-view detection and decoding aperture even in dynamic geometries.
(FR) La présente invention concerne un récepteur d'imagerie bimodale (DMIR) pouvant acquérir et maintenir des liaisons de communication optique en espace libre (FSOC) SOA sans cardan mécanique de précision. Contrairement à d'autres technologies FSOC, un DMIR peut fonctionner sans alignement spatial précis et sans étalonnage des codeurs spatiaux de l'émetteur ou du récepteur (pointage de précision) dans des géométries statiques (point à point fixes). Au lieu de cela, un DMIR utilise une sélection de faisceau de réception électronique pour acquérir et pour suivre des émetteurs à l'aide d'un pointage mécanique grossier et d'une ouverture unique. Et étant donné que le DMIR peut fonctionner à l'aide d'une seule ouverture, la présence d'une balise au niveau de l'émetteur n'est pas nécessaire puisque le DMIR ne passe pas d'une ouverture d'acquisition à champ de vision large à une ouverture de détection et de décodage à champ de vision étroit même dans des géométries dynamiques.
