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 1300 nm employing a handheld scanner.Transverse Scanning(110.4500) Imaging systemsOptical coherence tomography(170.0170) Medical optics and biotechnologyMedical optics and biotechnology(170.4500) Medical optics and biotechnologyComplex Ambiguity-Free Fourier Domain Optical Coherence Tomography through Transverse Scanningtext::journal::journal article::research article
