Abstract

A conventional Fourier-domain optical coherence tomography(FD-OCT) is improved to a line-field FD-OCT. The line-field FD-OCT is a conventional FD-OCT in its vertical axis, and a one-dimensional(1-D) imaging system in its lateral axis. Hence, depth and lateral information, which provide a 2-D OCT image, are simultaneously detected without any mechanical scan. Using an additional 1-D mechanical scan, which is realized by a galvano mirror in our system, a 3-D volume can be measured. Because the dimensions of mechanical scan are decreased compared with conventional FD-OCT, this system is capable of faster measurement.
