The present invention relates to a device for demultiplexing spectrum lines contained in an optical spectrum. This device comprises a energy separator (2a, 2b, 2c) and selective wavelength light reflectors (12), each selective wavelength light reflector having a wavelength bandpass that contains the spectral region associated with one of the lines and that, therefore, reflects only this particular line. Applications to surveying constructions, such as buildings and aircraft.

Ce dispositif comprend un séparateur en énergie (2a, 2b, 2c) et des réflecteurs de lumière sélectifs en longueur d'onde (12), chaque réflecteur sélectif ayant une bande passante en longueur d'onde qui contient le domaine spectral associé à l'une des raies et réfléchissant donc seulement cette raie. Application à la surveillance de structures telles que les bâtiments ou les aéronefs.
