Abstract

The invention relates to a system and a corresponding method for optical coherence tomography having at least one interferometer for emitting light with which a specimen is irradiated, a specimen arm comprising a specimen objective by means of which light emitted by the interferometer is focused in a focus lying within the specimen, a detector for collecting light which is reflected by the specimen, and a control unit for controlling the system such that during the collection alight, which is respectively reflected at different depths of the specimen, the imaging properties of the specimen objective are changed.
