Abstract
(EN)
A Light Detection And Ranging (LIDAR) measurement circuit includes a control circuit configured to receive respective detection signals output from one or more single-photon detectors in response to a plurality of photons incident thereon. The control circuit includes a photon counter circuit including a digital counter circuit and an analog counter circuit, the digital counter circuit being responsive to an output of the analog counter circuit or the analog counter circuit being responsive to an output of the digital counter circuit to count detection of respective photons of the plurality of photons based on the respective detection signals, and a time integration circuit configured to output a time integration signal representative of respective times of arrival indicated by the respective detection signals. The control circuit is configured to calculate an estimated time of arrival of the plurality of photons based on a ratio of the time integration signal and the count of the detection of the respective photons of the plurality of photons.

L'invention concerne un circuit de mesure de détection et estimation de distance par la lumière (LIDAR) qui comprend un circuit de commande configuré pour recevoir des signaux de détection respectifs émis par un ou plusieurs détecteurs de photon unique en réponse à une pluralité de photons incidents sur ceux-ci. Le circuit de commande comprend un circuit compteur de photons comprenant un circuit compteur numérique et un circuit compteur analogique, le circuit compteur numérique étant sensible à une sortie du circuit compteur analogique ou le circuit compteur analogique étant sensible à une sortie du circuit compteur numérique pour compter la détection de photons respectifs de la pluralité de photons sur la base des signaux de détection respectifs, et un circuit d'intégration temporelle configuré pour délivrer en sortie un signal d'intégration temporelle représentatif d'instants d'arrivée respectifs indiqués par les signaux de détection respectifs. Le circuit de commande est configuré pour calculer un instant d'arrivée estimé de la pluralité de photons sur la base d'un rapport du signal d'intégration temporelle et du comptage de la détection des photons respectifs de la pluralité de photons.
