Abstract
In order to investigate a specimen (30) with the aid of a microscope (20), dye particles (40, 42) in the specimen (30) are excited to fluoresce with the aid of a first illumination light beam (24). Fluorescent light proceeding from the specimen (30) is directed via an optical arrangement (34) onto an areal sensor (36), the optical arrangement (34) acting on the fluorescent light in such a way that sub-beams of the fluorescent light interfere with themselves, so that interference patterns produced as a result of the interference are imaged on a sensitive surface of the areal sensor (36) and sensed thereby. Positions of the dye particles (40, 42) within the specimen (30) are ascertained as a function of the interference patterns.
