Abstract

Full-range complex spectral domain (SD) optical coherence tomography (OCT) enables the removal of the complex conjugate artefact by measurement of the phase of the spectral interference signal. In order to retrieve the complex signals, the phase of the OCT signal has to be modulated in a well-defined way. For this purpose, different devices, such as piezo mirrors or electro-optic modulators, have been added to the instruments reported so far. We present a SD-OCT system capable of elimination of the complex conjugate artefact without using any additional phase modulating devices. A stable phase modulation is generated by displacing the galvo scanner mirror used for 2D imaging in such a way that the probe beam hits the mirror off its axis of rotation. Only a single measurement is necessary for the reconstruction of each complex valued depth profile, thus allowing for high-speed imaging. The method is demonstrated for full-range imaging of the anterior segments of human eyes in vivo.
