Abstract
A method and device for obtaining a sample with three-dimensional microscopy, in particular a thick biological sample and the fluorescence field emitted by the sample. One embodiment includes obtaining interferometric signals of a specimen, obtaining fluorescence signals emanating from the specimen, recording these signals, and processing these signals so as to reconstruct three-dimensional images of the specimen and of the field of fluorescence emitted by the specimen at a given time. Another embodiment includes a digital holography microscope, a fluorescence excitation source illuminating a specimen, where the microscope and the fluorescence excitation source cooperate to obtain interferometric signals of the specimen and obtain fluorescence signals emanating from the specimen, means for recording the interferometric signals and fluorescence signals, and means for processing the interferometric signals and the fluorescence signals so as to reconstruct three-dimensional images of the specimen and of the field of fluorescence emitted by the specimen at a given time.
