Paper Abstract

We have reported a technique of full-range imaging so-called a Dual-Detection Frequency Domain Optical Coherence Tomography (DD-FD-OCT), in which two spectra, representing real and imaginary components of a complex spectral interference, are simultaneously acquired by two detection channels. In this paper, we will discuss in detail a mirror rejection performance of DD-FD-OCT. Furthermore, we present an implementation of DD-FD-OCT for phase-resolved Doppler imaging. The DD-FD-OCT signal is achieved without manipulation of the phase relation between consecutive axial lines and hence its phase information is almost identical to that acquired by the conventional FD-OCT. As a result, the full-range DD-FD-OCT is fully applicable to phase-resolved Doppler imaging without either degradation in the fullrange performance or reduction in the velocity dynamic range in flow measurement. An in vivo flow imaging within biological samples using the DD-FD-OCT is demonstrated.
