    Abstract: The invention relates to a compensator system adapted to compensate for the angular dispersion of electromagnetic beams deflected by at least one acousto-optic deflector. The compensator system comprises: - a first lens group for spatially separating the deflected beams of different deflection angle and angular dispersion, - a compensator element having a first surface and a second surface that together work as prisms with tilt angles .beta. and prism opening angles ap that vary with the distance from the optical axis so as to compensate for the angular dispersion of the spatially separated deflected beams, - a second lens group arranged so as to substantially parallelise the different wavelength components of each deflected beam while maintaining the angular variation of the beams deflected at different acoustic frequencies. The invention further relates to a corresponding method for compensating for the angular dispersion of electromagnetic beams deflected by an acousto-optic deflector.

    Abstract: Método para escanear a lo largo de una trayectoria de escaneo tridimensional continua con un sistema de escáner (100) que comprende una primera pareja de deflectores acusto-ópticos (10) para desviar un punto focal de un haz electromagnético generado por un sistema de lentes consecutivas (200) que definen un eje óptico (z) en un plano xz, y una segunda pareja de deflectores acusto-ópticos (20) para desviar el punto focal en un plano y-z que es sustancialmente perpendicular al plano x-z, caracterizado por pasar el haz electromagnético a través de las parejas primera y segunda de deflectores acusto-ópticos (10, 20) mientras se proporcionan cambios en el tiempo de frecuencia acústica dependientes del tiempo, que cambian con el tiempo continuamente y no linealmente en los deflectores (12, 12') de la primera pareja de deflectores (10) y en los deflectores (22, 22') de la segunda pareja de deflectores (20) para provocar que el punto focal del haz electromagnético se mueva continuamente a lo largo de la trayectoria de escaneo.

    Abstract: The present invention relates to a focusing system (100) for focusing an electromagnetic beam for three-dimensional random access applications, the system comprising a first pair of acousto-optic deflectors (10) for focusing an electromagnetic beam in an X-Z plane, and a second pair of acousto-optic deflectors (20) for focusing an electromagnetic beam in a Y-Z plane being substantially perpendicular to the X-Z plane, characterised in that the second pair of acousto-optic deflectors (20) are arranged between the acousto-optic deflectors (12, 12') of the first pair of acousto-optic deflectors (10), such that the first and fourth acousto-optic deflectors (12, 12") of the system belong to the first pair of acousto-optic deflectors (10) and the second and third acousto-optic deflectors (22, 22") of the system belong to the second pair of acousto-optic deflectors (20).
