Abstract
An optical coherence tomograph that provides wavelength tunable source radiation and an illumination and measurement beam path, a dividing element that divides source radiation into illumination radiation and reference radiation, and collects measurement radiation. The illumination and measurement beam path has scanner. A detection beam path receives measurement radiation and reference radiation and conducts them onto at least one flat panel detector in a superposed manner. A beam splitter separates the measurement radiation from the illumination radiation. The beam splitter conducts the separated measurement radiation to the detection beam path and sets the numerical aperture of the illumination of the illumination field in the eye. An optical element sets the numerical aperture with which the measurement radiation is collected in the eye and a multi-perforated aperture defines the size of an object field and a number of object spots, from which the measurement radiation reaches the flat panel detector.
