Interferometric synthetic aperture microscopy with automated parameter evaluation and phase equalization preprocessing

摘要

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. As the proposed algorithm is phase sensitive, and phase stability is crucial, phase equalization preprocessing which allows compensating the phase error caused by object motion during scanning was proposed.
