Functional Fourier Domain Optical Coherence Tomography and its Applications

Novel optical coherence tomography (OCT) systems with ultralong depth range, ultrawide lateral field, and ultrahigh axial resolution are developed, which envision new medical applications. Typical applications of structural and functional OCT are presented. As a depth-resolved optical imaging modality with the merits of non-destruction, high-resolution, and high-speed, OCT is promising for applications in variety areas.
