Title (EN) OPTICAL WIRELESS COMMUNICATIONS SYSTEM
(FR) SYSTÈME OPTIQUE DE COMMUNICATIONS SANS FIL
Abstract:
(EN) There is a photovoltaic (PV) panel 10 including an array of photovoltaic (PV) elements (12). Each PV element (12) is stand alone and can be electronically addressed individually. The PV panel (10) also includes a number of spectral filters (14), in this example, a red filter (14r), a green filter (14g) and a blue filter (14b) arranged over some of the PV elements (12) to filter out the red, green and blue spectral components from white (combined red, green and blue) light emitted from a red-green-blue (RGB) transmitter. Data can be transmitted by modulating the spectral components of the RGB transmitter such that the data in each of the spectral components can be recovered from the electrical signal generated by the PV elements (12).
(FR) L'invention concerne un panneau photovoltaïque (PV) (10) comprenant un réseau d'éléments photovoltaïques (PV) (12). Chaque élément PV (12) est autonome et peut être géré électroniquement individuellement. Le panneau PV (10) comprend également un certain nombre de filtres spectraux (14), dans cet exemple, un filtre rouge (14r), un filtre vert (14g) et un filtre bleu (14b) disposés sur certains des éléments PV (12) afin de filtrer les composantes spectrales rouges, vertes et bleues à partir de lumière blanche (combinée rouge, verte et bleue) émise par un émetteur rouge-vert-bleu (RVB). Des données peuvent être transmises par modulation des composantes spectrales de l'émetteur RVB de telle sorte que les données dans chacune des composantes spectrales peuvent être récupérées à partir du signal électrique généré par les éléments PV (12).
