CA 2640311

The invention describes an optical multiplexer for increasing optical data collection efficiency across at least two fields of view. The optical multiplexer includes a first optical path for operatively receiving optical data from a first field of view and at least one beam deflection system for operatively receiving optical data from at least a second field of view. The optical multiplexer also includes an optical train for focusing the optical data passing through the optical train onto adjacent sections of a focal plane array. The invention provides improvements including expanded across-track swaths, higher spatial resolution, imaging of real-time references on every frame, coincident imaging along separate paths, stereo imaging and other increases in imaging functionality.

L'invention concerne un multiplexeur optique qui permet d'augmenter le rendement de collecte de données optiques dans au moins deux champs de vision. Le multiplexeur optique comprend un premier parcours optique qui reçoit en fonctionnement des données optiques d'un premier champ de vision et au moins un système de déviation de faisceau qui permet de recevoir fonctionnellement des données optiques d'au moins un deuxième champ de vision. Le multiplexeur optique comprend également une chaîne optique qui concentre les données optiques qui traversent la chaîne optique sur des parties adjacentes d'une batterie focale plane. L'invention offre des améliorations, notamment un plus large recouvrement entre les balayages, une plus haute résolution spatiale, la formation de références en temps réel sur chaque trame, la formation d'images coïncidentes sur des parcours séparés, l'imagerie stéréo et d'autres extensions des fonctions d'imagerie.
