Abstract[English]
Disclosed is a spatial estimation system. The system is configured to: provide to first outgoing light with a first reception window ending at a time based on the system's maximum range, provide second outgoing light with a second reception window ending at a time based on the maximum range, provide, during the first reception window, a first local oscillator signal to a homodyne receiver architecture based on the first outgoing light, and provide, during the first reception window, a second local oscillator signal to the homodyne receiver architecture based on the second outgoing light. The first reception window and the second reception window overlap in time. There is a difference in frequency or modulation between the first and the second outgoing light. The spatial estimation system is further configured to: receive, during the first reception window, reflected first outgoing light and/or reflected second outgoing light; and disambiguate reflected light signals based on the difference in the frequency or modulation.[French]
Est divulgué un système d'estimation spatiale. Le système est configuré pour : fournir à une première lumière sortante une première fenêtre de réception se terminant à un instant en fonction de la plage maximale du système, fournir à une seconde lumière sortante une seconde fenêtre de réception se terminant à un instant en fonction de la plage maximale, fournir, pendant la première fenêtre de réception, un premier signal d'oscillateur local à une architecture de récepteur homodyne en fonction de la première lumière sortante, et fournir, pendant la première fenêtre de réception, un second signal d'oscillateur local à l'architecture de récepteur homodyne en fonction de la seconde lumière sortante. La première fenêtre de réception et la seconde fenêtre de réception se chevauchent dans le temps. Il existe une différence de fréquence ou de modulation entre la première et la seconde lumière sortante. Le système d'estimation spatiale est en outre configuré pour : recevoir, pendant la première fenêtre de réception, une première lumière sortante réfléchie et/ou une seconde lumière sortante réfléchie ; et désambiguïser des signaux de lumière réfléchis en fonction de la différence de fréquence ou de modulation.
