Method, a device and a system for numerical data processing

A computer-implemented method for numerical processing of input data, which input data have the form of N measurement results forming a vector with coordinates numbered from 0 to N-1, and which input data have been registered in a detector, in an optical coherence tomography device, OCT, during a process involving:

• the emission of light by a light source,
• splitting the light in a coupler into at least two paths, meaning:
• at least one reference path, in which a reference light beam is reflected from a mirror,
• at least one sample path, in which a sample light beam is reflected from the object under examination,
• reflecting said reference light beam in at least one reference path from the mirror, and
• reflecting said sample light beam in at least one sample path from the object under examination,
• merging and interference of the reference light beam and the sample light beam in the coupler,
• optional passing of the merged light beams across a diffraction grating,
• recording the data in the form of a spectrum of merged light beams within a specified light wavelength range by means of said detector as said vector of N measurement results,
• k-space resampling a first subset of input data, i.e. the input data saved in said vector of N measurement results, as coordinates numbered from n1in_min to n1in_max, where 0≤n1in_min<n1in_max≤N−1, which k-space resampling is described by means of a first set of calibration parameters, into a first subset of output data, in which first subset of output data, the values of the output data, meaning the data after resampling, are saved in the form of a first vector of output data, with coordinates numbered from n1out_min to n1out_max,
• characterised in that it comprises the step of
• at the user's request, resampling a second subset of input data, i.e. the input data saved in said vector of N measurement results as coordinates numbered from n2in_min to n2in_max, where 0≤n2in_min<n2in_max≤N−1, which resampling is described by means of a second set of calibration parameters, into a second subset of output data, in which second subset of output data the values of the output data, meaning the data after k-space resampling, are saved in the form of a second vector of output data, with coordinates numbered from n2out_min to n2out_max, the first subset of input data being different in at least one element from the second subset of input data, and/or the first set of calibration parameters being different in at least one parameter from the second set of calibration parameters, wherein the first output data resampled by means of the first calibration parameters has a greater or narrower spectral width of wavelength in comparison to the second output data resampled by means of the second calibration parameters.
