Abstract:
(EN) A system for diffusing audio signals by means of an optical radiation, wherein said system is characterized in that it comprises: - at least one first and one second optical transmitting module (99', 99"), each comprising at least one photoemitter (100) emitting an amplitude modulated optical radiation, said first and said second optical transmitting module (99', 99") transmitting a first and a second modulated optical radiation according to a first and respectively a second signal at least of the audio type (s1(t), s2(t)); - at least one optical receiving module (199), comprising: - at least one photoreceiver (200) adapted to receive said amplitude modulated optical radiation from at least one of said optical transmitting modules (99', 99"), - at least one AM demodulator (202), electrically connected to said at least one photoreceiver (200), wherein said optical receiving module (199) is configured to generate, on at least one first output thereof, a replica electrical signal (s'(t)), replicating said audio signal transmitted from said at least one first and/or second optical transmitting module, so that: - if only the first optical radiation is received, it replicates said first audio signal (s1(t)); - if only the second optical radiation is received, it replicates said second audio signal (s2(t)); - if both the first optical radiation and the second optical radiation are received simultaneously, it replicates said first audio signal (s1(t)) mixed with said second audio signal (s2(t)), wherein the at least instantaneous intensity of the replica of said first audio signal (s1(t)) and of the replica of said second audio signal (s2(t)) is proportional respectively to the intensity of said first optical radiation and/or of the modulation thereof, and to the intensity of said second optical radiation and/or of the modulation thereof.
(FR) Un système de diffusion de signaux audio au moyen d'un rayonnement optique, ledit système étant caractérisé en ce qu'il comprend : au moins un premier et un second module de transmission optique (99', 99"), comprenant chacun au moins un photoémetteur (100) émettant un rayonnement optique modulé en amplitude, lesdits premier et second modules de transmission optique (99', 99") transmettant un premier et un second rayonnement optique modulé selon un premier et respectivement un second signal au moins du type audio (s1(t), s2(t)); au moins un module de réception optique (199), comprenant : au moins un photorécepteur (200) apte à recevoir ledit rayonnement optique modulé en amplitude à partir d'au moins un desdits modules de transmission optique (99', 99"), au moins un démodulateur AM (202), connecté électriquement audit(s) photorécepteur(s) (200), ledit module de réception optique (199) est configuré pour générer, sur au moins une première sortie de celui-ci, un signal électrique de réplique (s'(t)), reproduire ledit signal audio transmis à partir dudit/desdits premier(s) et/ou deuxième module de transmission optique, de sorte que: - si seul le premier rayonnement optique est reçu, il reproduit ledit premier signal audio (s1(t)); -si seul le second rayonnement optique est reçu, il reproduit ledit second signal audio (s2(t)); -si à la fois le premier rayonnement optique et le second rayonnement optique sont reçus simultanément, il reproduit ledit premier signal audio (s1(t)) mélangé avec ledit second signal audio (s2(t)), l'intensité au moins instantanée de la réplique dudit premier signal audio (s1(t)) et de la réplique dudit deuxième signal audio (s2 (t)) est proportionnelle respectivement à l'intensité dudit premier rayonnement optique et/ou à sa modulation, et à l'intensité dudit deuxième rayonnement optique et/ou à sa modulation.
