“…It is widely used in biological and medical applications [1][2][3][4]. One of the promising ways of OCT development aimed at enhancing image informativity is an increase of resolution, lateral resolution in particular [5][6][7][8][9][10]. However, increasing lateral resolution of an OCT system by sharpening the scanning beam focal spot leads to an increase of diffraction divergence and to a corresponding decrease of focal depth.…”

A method of OCT imaging with a resolution throughout the investigated volume equal to the resolution in the best-focused region is described. It is based on summation of three-dimensional scattered field distributions at the wavelengths determined by OCT source spectral decomposition. A method of finding parameters needed for algorithmic realization of the summation is also proposed. The proposed approaches are tested on several model media, including biological ones.

“…Optical coherence tomography (OCT) is an emerging technique for cross-sectional imaging widely used in nondestructive investigation of internal structure of different (first of all biological) samples [1][2][3][4]. Several ways of providing more information from OCT images are introduced, while the most straightforward way is improving system resolution [5][6][7][8][9][10]. It is well known that lateral resolution of the OCT setup conflicts with imaging depth.…”

Based on the fact that spectral domain (SD) optical coherence tomography (OCT) data can be treated as digital holography (DH) data acquired pointwise, we develop a spectral refocusing algorithm and show its ability to shift the focal region of OCT images obtained from SD OCT data acquired with a tightly focused scanning beam. Although refocusing itself depends on the refractive index of the studied media, we propose a procedure capable of restoring images with resolution equal to the resolution in the focal plane in the whole volume even in case of unknown refractive index of the media. As the proposed refocusing method operates with phases of the 3D Fourier spectrum of the SD OCT signal, it is very sensitive to the object motion during data acquisition. Thus, we also propose phase equalization preprocessing, which allows compensating the influence of such motions.
