Paper Abstract

In this manuscript the application of a novel technique for axial resolution improvement in Fourier Domain Optical Coherence Tomography (FDOCT) is demonstrated. Axial resolution in FDOCT can be improved by ~7x without the need for a broader bandwidth light source using modulated deconvolution. In FDOCT the real part of FFT of each interferofram is modulated by a frequency which depends on the position of the interferogram. If an interferogram is shifted slightly, the frequency of the real part of the FFT changes. By adding two shifted interferograms, beating can be appeared in the OCT A-Scans. Subsequently deconvolution with suitable kernels can produce a significant resolution improvement in the FDOCT image.
