Patent number: 8559085Abstract: A focusing system for focusing an electromagnetic beam for three-dimensional random access applications comprises a first pair of acousto-optic deflectors for focusing an electromagnetic beam in an X-Z plane, and a second pair of acousto-optic deflectors for focusing an electromagnetic beam in a Y-Z plane substantially perpendicular to the X-Z plane. The second pair of acousto-optic deflectors is arranged between the acousto-optic deflectors of the first pair of acousto-optic deflectors such that the first and fourth acousto-optic deflectors of the system belong to the first pair of acousto-optic deflectors and the second and third acousto-optic deflectors of the system belong to the second pair of acousto-optic deflectors.Type: GrantFiled: December 30, 2009Date of Patent: October 15, 2013Assignee: Femtonics Kft.Inventors: Pal Andor Maak, J. Balazs Rozsa, Gergely Katona, E. Szilveszter Vizi, Mate Veress, Attila Csakanyi, Gergely Szalay
