Paper Abstract

High speed complex full-range Fourier domain optical coherence tomography (FD-OCT) is demonstrated. In this FD-OCT phase modulation of a reference beam (M-scan) and transversal scanning (B-scan) are performed simultaneously. Because of this simultaneous BM-scan, this FD-OCT requires only a single A-scan for each single transversal position. The Fourier transform method is applied along the direction of the B-scan to reconstruct complex spectra, and the complex spectra compose a full-range OCT image. A simple but slow version of this FD-OCT visualizes the cross-section of a plastic plate. A modified fast version of this FD-OCT investigates a sweat duct in a finger pad in vivo, and visualizes it with 100 ms acquisition time.
