Abstract
A method of numerical compensating of OCT image distortion provided by fluctuations of the distance to the object has been proposed and verified experimentally. The method is based on the analysis of inter A-scan phase shifts caused by micrometer-scale displacements, and the subsequent compensation of the displacements by phase-frequency correction in the spectral space. The efficiency of the method is demonstrated in model experiments with harmonic and random movements of a scattering object, as well as during in vivo imaging of the retina of the human eye.
