Abstract

Une source d'émission d'une onde Terahertz comprend un dispositif source de deux ondes incidentes ν1 et ν2 choisies pour que leur fréquence différence νd soit de l'ordre du Terahertz. Ces ondes sont transportées par un guide 2 jusqu'à la surface de détection d'un photodétecteur 30 muni d'une antenne 31.Le photodétecteur et l'antenne forme une tête d'émission miniature 3.Cette tête d'émission miniature et le guide d'onde 2 peuvent être intégrés à un montage de type sonde invasive, et permet des utilisations in vivo.L'invention s'applique à des systèmes d'imagerie, notamment médicale, et à un système de traitement par hyperthermie.A source of emission of a Terahertz wave comprises a source device of two incident waves ν1 and ν2 chosen so that their difference frequency νd is of the order of Terahertz. These waves are transported by a guide 2 to the detection surface of a photodetector 30 provided with an antenna 31. The photodetector and the antenna form a miniature emission head 3.This miniature emission head and the waveguide 2 can be integrated into an invasive probe type assembly, and allows in vivo uses. The invention applies to imaging systems, in particular medical systems, and to a hyperthermia treatment system.
