| description | Provided is a terahertz beam steering apparatus and method capable of scanning a terahertz beam at high speed and over a wide angle. A laser device (12) for generating a first laser light (1) and a second laser light (2) which have different wavelengths, a laser optical system (14) for focusing the first laser light (1) and the second laser light (2) on the same common focal point (14b), and a terahertz generator (16) which is positioned at the common focal point and generates a terahertz beam (4) by difference frequency mixing are provided. The laser optical system (14) is designed to enable changing of the relative incident angle ?i between the first laser light and the second laser light at the terahertz generator.
L'invention porte sur un appareil d'orientation de faisceau térahertz et sur un procédé capable de balayer un faisceau térahertz à vitesse élevée et sur un grand angle. Un dispositif laser (12) pour générer une première lumière laser (1) et une seconde lumière laser (2) qui ont différentes longueurs d'onde, un système optique laser (14) pour focaliser la première lumière laser (1) et la seconde lumière laser (2) sur le même point focal commun (14b) et un générateur térahertz (16) qui est positionné au niveau du point focal commun et génère un faisceau térahertz (4) par mélange de fréquence de différence sont fournis. Le système optique laser (14) est mis au point pour permettre le changement de l'angle incident relatif ?i entre la première lumière laser et la seconde lumière laser au niveau du générateur térahertz. |
