According to various aspects a light detection system (100, 300a-300e, 400a-400d) is provided, the light detection system (100, 300a-300e, 400a-400d) including: a detector (102, 202, 302, 402a-402d) configured to provide a received light signal (104, 204-2); and a processing circuit (106, 240, 340a-340e, 404) configured to: provide a plurality of branched signals (108, 210) each being representative of the received light signal (104, 204-2); and combine the plurality of branched signals (108, 210) with one another to provide a combined signal (110, 218), wherein the plurality of branched signals (108, 210) differ from one another in such a way that, as a result of the combination, respective signal components (108s) of the plurality of branched signals (108, 210) combine in a constructive manner and respective noise components (108n) of the plurality of branched signals (108, 210) combine in an at least partially destructive manner. Selon divers aspects, l'invention concerne un système de détection de lumière (100, 300a-300e, 400a-400d), le système de détection de lumière (100, 300a-300e, 400a-400d) comprenant : un détecteur (102, 202, 302, 402a-402d) configuré pour fournir un signal lumineux reçu (104, 204-2) ; et un circuit de traitement (106, 240, 340a-340e, 404) configuré pour : fournir plusieurs signaux ramifiés (108, 210), chacun étant représentatif du signal lumineux reçu (104, 204-2) ; et combiner lesdits plusieurs signaux ramifiés (108, 210) les uns avec les autres pour fournir un signal combiné (110, 218), lesdits plusieurs signaux ramifiés (108, 210) différant les uns des autres de telle sorte que, en résultat de la combinaison, les composants de signal respectifs (108s) desdits plusieurs signaux ramifiés (108, 210) se combinent de manière constructive et les composantes de bruit respectives (108n) desdits plusieurs signaux ramifiés (108, 210) se combinent de manière au moins partiellement destructive.
