Leitgeb, R. A.Michaely, R.Lasser, T.Sekhar, S. C.2008-03-062008-03-062008-03-062008https://infoscience.epfl.ch/handle/20.500.14299/19859We introduce a simple and cheap method for phase-shifting Fourier domain optical coherence tomography (FDOCT) that does not need additional devices and can easily be implemented. A small beam offset at the fast beam-scanning mirror introduces a causal phase shift, which can be used for B-scan-based complex image reconstruction. We derive the conditions for optimal conjugate suppression and demonstrate the method on human skin in vivo for spectrometer-based FDOCT operating at 1300nm employing a handheld scanner.(110.4500) Imaging systemsOptical coherence tomography(170.0170) Medical optics and biotechnologyMedical optics and biotechnology(170.4500) Medical optics and biotechnologytext::journal::journal article
