Title
(EN) DEVICE FOR OPTICALLY CONVERTING A PLURALITY OF BEAMS
(FR) DISPOSITIF DE CONVERSION OPTIQUE D'UNE PLURALITE DE FAISCEAUX
Abstract
(EN)
An optical apparatus for converting an incoming array of light beams by interchanging the horizontal and vertical components of each beam, the apparatus having a series of grooves, one groove for each incoming beam, where each groove comprises two reflecting surfaces: a first reflecting surface operating to intercept the corresponding beam and reflect it to a second reflecting surface along a first path of travel, that is folded with respect to the incoming beam's direction of propagation, while rotating one of the beam's azimuths, and the second reflecting surface operating to intercept the beam reflected off the first surface and to direct it along a second path of travel, folded with respect to the first path of travel, while rotating the beam's other azimuth.
(FR)
Un dispositif optique permet de convertir un groupe incident de faisceaux lumineux en permutant les composantes horizontales et verticales de chaque faisceau. Le dispositif comporte une série de rainures, chaque rainure étant prévue pour chaque faisceau incident et comprenant deux surfaces réfléchissantes: une première surface réfléchissante conçue pour intercepter le faisceau correspondant et le réfléchir sur une seconde surface réfléchissante le long d'une première trajectoire, qui est repliée par rapport au sens de propagation du faisceau incident, tout en faisant tourner un des azimuts du faisceau, et la seconde surface réfléchissante conçue pour intercepter le faisceau réfléchi à partir de la première surface et le diriger le long d'une seconde trajectoire, repliée par rapport à la première trajectoire, tout en faisant tourner l'autre azimut du faisceau.
