Claim Text:
1. Method for measuring the spatial and velocity distribution of scattering structures of a sample of semitransparent matter comprising the steps of acquiring sequentially a plurality of spectral optical coherence tomography spectra I(k) comprising data belonging to a real image and data belonging to a mirror image, for which time intervals between two recordings are known so that a data set I(k, t) representing the time dependence of the recorded spectra is generated, transforming said data set I(k, t) to a data set I(z, v) by performing a k-z transformation and a t-v transformation, where z represents the positions of back-scattering structures of the sample along the axis of the incident light and v represents the velocity component along said the axis of back-scattering structures of the sample, the method comprising: selecting a velocity v imposing a Doppler shift on a light, whereby a sample light and a reference light used in the method appear at a point of recombination as originating from sources moving relatively to each other with the selected velocity v
