Abstract
(EN)
Disclosed is a method of operating an array of receiver devices (6) as a phased array. The receiver devices (6) are in a fixed mutual relationship within a zone (2) and each receiver device (6) comprises a photovoltaic element (16). The method involves receiving a signal from within the zone (2) at a plurality of the receiver devices (6) to generate a plurality of received signals and processing the received signals using at least one phase difference therebetween. The method also involves directing a beam of light (36) from a unit (8) located within the zone (2) to the photovoltaic elements (16), thereby providing power to said receiver devices (6). The invention extends to an array of transmitter devices and to an array of both transmitter and receiver devices.

L'invention concerne un procédé de fonctionnement d'un réseau de dispositifs récepteurs (6) en tant que réseau piloté en phase. Les dispositifs récepteurs (6) sont dans une relation mutuelle fixe dans une zone (2) et chaque dispositif récepteur (6) comprend un élément photovoltaïque (16). Le procédé consiste à recevoir un signal provenant de l'intérieur de la zone (2) au niveau d'une pluralité des dispositifs récepteurs (6) pour générer une pluralité de signaux reçus et à traiter les signaux reçus à l'aide d'au moins une différence de phase entre ceux-ci. Le procédé consiste également à diriger un faisceau de lumière (36) à partir d'une unité (8) située à l'intérieur de la zone (2) vers les éléments photovoltaïques (16), fournissant ainsi de l'énergie auxdits dispositifs récepteurs (6). L'invention s'étend à un réseau de dispositifs émetteurs et à un réseau de dispositifs émetteurs et récepteurs.
