Abstract

Standard high-speed Fourier domain optical coherence tomography (FD-OCT) and a modified version of FD-OCT; a line-field FD-OCT (LF-FDOCT) are demonstrated. LF-FDOCT is using the principle of FD-OCT for its depth resolution and a one-dimensional imaging optics for its one-dimensional lateral resolution. A mechanical C-scan drived by a galvano scanner is introduced into the FD-FDOCT, which shows a cross sectional OCT image without any mechanical scanning. The improved version of FD-OCT visualizes the three-dimensional structure of a sample with only one-dimensional scanning. Both standard FD-OCT and LF-FDOCT are applied to dermatological applications and visualize the inner structure of an in vivo human fingerpad.
