Random access stimulated emission depletion (STED) microscopy

摘要

Optical scanning system, comprising an optical system for guiding a first and a second light beam, and deflector devices for deflecting first and second light beams in a directionally variable manner. The deflector devices comprise at least one acousto-optic deflector, and the optical system is arranged in such a way that the first and second light beams are counter-propagating through the acousto-optic deflector, which is controllable for deflecting the first and second light beams simultaneously or in pulse sequence. STED microscopy apparatus comprising an optical scanning system based on acousto-optic deflectors.
