发明名称 誘導放出抑制顕微鏡システム
摘要 <p>The invention discloses an optical microscopy system (10) for stimulated emission depletion (STED) of an object (O). An optical element (6) is applied for focusing a first excitation (1) and a second depletion (2) beam on the object thereby defining a common optical path (OP) for both the first and the second beam. A phase modifying member (5) is inserted in the common optical path (OP), and the phase modifying member is optically arranged for leaving the wavefront of the first beam substantially unchanged, and for changing the wavefront of the second beam (2′) so as to create an undepleted region of interest (ROI) in the object. The first beam and the second beam have a common optical path because the phase modifying member adapts the wavefront or phase in such a way that it has no effect on the first beam, while on the second beam it gives rise to a wavefront, or phase change, resulting in a depleted region in the object (e.g. to the donut shaped spot) at the focal plane. The invention facilitates smaller and/or improved optical designs for STED microscopy; this is particularly relevant for medical in-vivo imaging, e.g. endoscopes and catheters.</p>
