Abstract
A method for holoscopic, optical coherence tomography for an object, wherein the method includes providing source radiation and splitting the source radiation into illumination radiation and reference radiation, illuminating an illumination field on the object with illumination radiation, said illumination field having an areal extent transverse to the direction of incidence, collecting illumination radiation scattered back from the object as measurement radiation, separating the measurement radiation collected from the object from the illumination radiation, and overlaying the measurement radiation with reference radiation and detecting an interference signal of the overlaid radiations with at least one areal detector with a two-dimensional extent, wherein the object in the illumination field is simultaneously illuminated by more than one spatial radiation mode, wherein the radiation modes of the illumination in the illumination field are spatially and temporally coherent with one another but have a fixed phase difference from one another.
