Complex Ambiguity-Free Fourier Domain Optical Coherence Tomography through Transverse Scanning

R.A. Leitgeb, R. Michaely, T. Lasser, S.C. Sekhar

Optics Letters, vol. 32, no. 23, pp. 3453-3455, December 2007.


We 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 1300 nm employing a handheld scanner.

This article has been selected for publication in The Virtual Journal for Biomedical Optics, vol. 3, no. 1, January 29, 2008. This re-publication is available here.
