Definitions

  • This invention refers to a method and to a device for the implementation of said method, to spread homogeneously a radiative spectrum in substrates (solid, liquid and gaseous), saturating volumes in a pervasive and distributed way, with one or two inlet points, fitted to ensure constancy of diffusion, said two inlet points being able to be supplied simultaneously or in following times.
  • the power can be supplied using natural and/or artificial sources.

  • the device is characterized in that it comprises one or more side emitting optical fibers, each one of said optical fibers comprising two parallel branches, of outward and of return located close together, said parallel branches being enclosed in a sandwich made with a pair of sheets transparent to the radiative spectrum of interest, said one or more optical fibers being provided with at least one inlet through which a signal is inserted, said signal spreading in said solids, liquids, vapours or gaseus mediums through the lateral emission of said one or more optical fibers.
  • a device according to the invention allows, for example, to spray in any volume in a pervasive and distributed mode, a radiative spectrum for the development or the correction of processes (e.g. crops vegetable and not, land or sea, or industrial processes).
  • processes e.g. crops vegetable and not, land or sea, or industrial processes.
  • the pervasive and distributed mode is achieved thanks to the possibility to prepare the optical fiber of the device, inside the volume occupied by said solids, liquids, vapours or gaseus mediums, then to distribute anywhere the radiative spectrum of interest, with density at will and compatible with the levels of transparency of said solids, liquids, vapours or gaseus mediums with reference to the radiative spectrum of interest.

Abstract

La présente invention concerne un procédé et un dispositif pour la mise en œuvre dudit procédé, pour disperser un spectre radiatif de manière homogène dans des substrats (solides, liquides et gazeux), des volumes de saturation de manière omniprésente et répartie, à l'aide d'un ou de deux points d'entrée, conçus pour assurer une constance de diffusion, lesdits deux points d'entrée pouvant être alimentés simultanément ou à la suite. Le procédé est caractérisé en ce qu'il utilise une ou plusieurs fibres optiques à émission latérale (1, 10) immergées dans lesdits milieux solides, liquides, de vapeurs ou gazeux, ladite ou lesdites fibres optiques (1, 10) étant agencées de sorte qu'un signal constitué par ledit spectre radiatif, qui est introduit dans ladite ou lesdites fibres optiques (1, 10), soit réparti de manière sensiblement uniforme dans lesdits milieux solides, liquides, de vapeurs ou gazeux. Le dispositif est caractérisé en ce qu'il comprend une ou plusieurs fibres optiques à émission latérale (1, 10), chacune desdites fibres optiques (1, 10) comprenant deux branches parallèles, une vers l'extérieur (1a, 10a) et une de retour (1b, 10b) proches l'une de l'autre, lesdites branches parallèles étant enfermées dans un sandwich (4, 4a) formé d'une paire de feuilles transparentes pour le spectre radiatif d'intérêt, ladite ou lesdites fibres optiques (1, 10) étant pourvues d'au moins une entrée (2 ou 3) par laquelle un signal (F1 ou F2) est inséré, ledit signal (F1 ou F2) se dispersant dans lesdits milieux solides, liquides, de vapeurs ou gazeux par l'intermédiaire de l'émission latérale de ladite ou desdites fibres optiques (1, 10).
