Abstract
The invention relates to a system and to a corresponding method for optical coherence tomography having an interferometer () which has a beam splitter (), a first reflector () and a reflector () the optical distance (I) of which from the beam splitter () is changeable by a speed (v), and a detector () for collecting light which is reflected by a specimen () to be examined. In order to reduce the times required for the most reliable possible recording of interference patterns, provision is made such that the intensity of the light (or) injected into the interferometer () or emitted by the interferometer () is modulated with a modulation frequency (f) which is not equal to the Doppler frequency (f), the Doppler frequency (f) being given by twice the ratio of the speed (v) of the change of the optical distance (I) between the reflector () and the beam splitter () to the average wavelength (λ) of the injected light ():=2.
