Claim:
1. A method for performing optical coherence tomography, the method comprising the steps of: successive sampling of an interference pattern at different depths within a depth range of an object to obtain a plurality of original initial image values at the different depths within the depth range of the object using optical coherence tomography equipment including a reference mirror, the successive sampling of the interference pattern being performed by successively detecting light reflected or backscattered from the object during a movement of the reference mirror; and obtaining a plurality of initial image values by combining at least two of the plurality of original initial image values, which were obtained at the different depths within the depth range of the object, to one initial image value, wherein the plurality of initial image values are located on a three-dimensional regular grid and adjacent initial image values are equally spaced apart in all three spatial dimensions, and the plurality of initial image values define at least two two-dimensional images of the object in planes of the object that are spaced apart from one another; and interpolating the plurality of initial image values of the at least two two-dimensional initial images in three-dimensional space by at least one of trilinear interpolation, triquadratic interpolation, tricubic interpolation, and multi-variate interpolation in the three-dimensional regular grid on which the plurality of initial image values of the at least two two-dimensional initial images are located to obtain interpolation values that form a two-dimensional final image.
