Abstract

The invention lies in the field of optical metrology and related to optical coherence tomography (OCT). In particular, the invention relates to an apparatus and a method for the depth-dependent adaptation of the dynamic range of an OCT system to the profile of the backscattered power to be measured. The dynamic range of the measuring method can therefore be decoupled from the dynamic range of the analog/digital converter used. The invention is used, in particular, in the characterization of strongly scattering or strongly absorbing biological or technical samples.
