DISPOSITIF DE DEMULTIPLEXAGE DES RAIES SPECTRALES CONTENUES DANS UN SPECTRE OPTIQUE

摘要

The invention concerns a device for demultiplexing light paths contained in an optical spectrum, comprising an energy separator (2a, 2b, 2c) and selective wavelength light reflectors (12) each selective reflector having wavelength bandpass containing the spectral range associated with one of the paths, hence reflecting only this path. The invention is useful for monitoring structures such as buildings or aircraft.
