Abstract
(EN) An optical sensing system (100) for performing distance measurements. The optical sensing system comprises an emitter (110) configured to emit electromagnetic radiation modulated at a known frequency. The optical sensing system further comprises a detector (130) configured to sample incident electromagnetic radiation at the known frequency, convert the sampled electromagnetic radiation into charge carriers, and collect the charge carriers in a storage component (IG1,IG2;IG10,IG20,IG30,IG40) to produce an electronic signal. The optical sensing system further comprises a processor (150) configured to determine a correction by applying a non-linear polynomial function to the electronic signal.
(FR) L'invention concerne un système de détection optique (100) pour effectuer des mesures de distance. Le système de détection optique comprend un émetteur (110) configuré pour émettre un rayonnement électromagnétique modulé à une fréquence connue. Le système de détection optique comprend en outre un détecteur (130) configuré pour échantillonner un rayonnement électromagnétique incident à la fréquence connue, convertir le rayonnement électromagnétique échantillonné en porteurs de charge et collecter les porteurs de charge dans un composant de stockage (IG1, IG2 ; IG10, IG20, IG30, IG40) pour produire un signal électronique. Le système de détection optique comprend en outre un processeur (150) configuré pour déterminer une correction par application d'une fonction polynomiale non linéaire au signal électronique.
