Abstract

An optical setup for a full range complex Fourier domain optical coherence tomography is proposed and the associated features discussed. We propose a novel interferometric platform based on a quadrature Mach-Zehnder interferometer with a 3 times 3 fiber coupler. This interferometric configuration is used in a homodyne configuration and the complex interferometric signal is reconstructed so the complex conjugate ambiguity is removed. A fast swept laser source with a bandwidth of 100 nm is used as light source. The depth information is extracted through inverse Fourier transform of the complex interferometric signal. Tomographic images of a human fingerprint were displayed.
