Optical coherence tomography for measurement on the retina

An optical coherence tomograph for examining a scattering sample to be placed in an object area, the optical coherence tomograph comprising:

• an illumination source that emits source radiation of sweepable wavelength;
• a dividing element that divides the source radiation into a reference beam path and an illumination beam path for illuminating the object area with illuminating radiation;
• optics in the illumination beam path that distribute the illumination radiation into several object spots and that project these object spots to the object area, and a scanner that adjusts the lateral position of the object spots in the object area;
• a detection beam path collecting radiation scattered at the object spots as measurement radiation and superimposing this measurement radiation with reference radiation guided through the reference beam path and guiding the superimposed radiations to a spatially resolving detector comprising pixels, wherein the measurement radiation from an individual object spot is guided to a detector spot covering several pixels of the detector with the detector generating signals therefrom;
• and
• a control device processing the signals generated by the detector and generating therefrom an image of a sample provided in the object area.
