Title
(EN) ROLLING-SHUTTER IMAGING SYSTEM WITH SYNCHRONIZED SCANNING ILLUMINATION AND METHODS FOR HIGHER-RESOLUTION IMAGING

Abstract
(EN)
Embodiments of a rolling-shutter imaging system with synchronized scanning illumination and methods for higher-resolution imaging are generally described herein. In some embodiments, the imaging system includes a focal plane array (FPA) and a read-out integrated circuit (ROIC) configured to activate only a portion of the FPA during an integration time. The imaging system also includes a scanner synchronized with the ROIC to illuminate only a portion of a sensor field-of-view (FOV) of the FPA within a scene that corresponds to at least the activated portion of the FPA. The imaging system may also include beamforming optics to generate a beam of light to illuminate the portion of the sensor FOV corresponding to portion of the FPA that is activated.

Des modes de réalisation de la présente invention portent sur un système d'imagerie d'obturateur à rideaux avec éclairage par balayage synchronisé et des procédés d'imagerie de résolution supérieure. Selon certains modes de réalisation, le système d'imagerie comprend un réseau de plans focaux (FPA) et un circuit intégré de lecture (ROIC) configuré pour activer uniquement une partie du FPA durant un temps d'intégration. Le système d'imagerie comprend également un scanner synchronisé avec le ROIC pour éclairer uniquement une partie d'un champ de vision (FOV) de capteur du FPA dans une scène qui correspond à au moins la partie activée du FPA. Le système d'imagerie peut également comprendre une optique de formation de faisceau pour générer un faisceau de lumière pour éclairer la partie du FOV de capteur correspondant à la partie du FPA qui est activée.
