    Abstract

    It has been shown that frequency domain optical coherence tomography (FD-OCT) systems achieve higher sensitivities compared to time domain optical coherence tomography (OCT) systems. However, the obscure object structure due to the mirror image generated by the Fourier transform is one of the remaining issues in the FD-OCT. We designed and developed what we believe to be a novel full range FD-OCT system that we refer to as the dual detection full range frequency domain optical coherence tomography (DD-FDOCT) that enables the instantaneous retrieval of quadrature components of the complex interferometric signal. The DD-FDOCT system enables full range imaging without loss of speed, and it may be less sensitive to phase error generated by involuntary movements of the subject compared to the other established full range OCT systems, because it uses two signals with a phase difference of pi/2 obtained simultaneously from two detection arms to remove mirror images at all depths.
