| 摘要 |
The invention relates to a microscope, comprising an imaging lens (4) for imaging a sample (3) on a detector and means for illuminating the sample (3) with a light layer (7) in the focus plane of the imaging lens (4), comprising an illumination source (1) emitting coherent light. In a microscope of said kind, the means for illumination comprise a Bessel lens (8, 10), creating at least two plane waves (6) from the light beam (5) and predefining propagation directions for the plane waves (6), wherein the propagation direction of each of the plane waves (6) forms an acute angle with the focus plane, the amount of the angle being the same for each of the plane waves (6), such that the plane waves (6) constructively interfere in the focus plane, thus creating a light layer (7). In a similar way, the means for illumination can also comprise an optical element, with which a rotationally symmetrical Bessel beam is created from the light beam (5), for dynamically creating a light layer (7). |
