Three‐dimensional (3D) optical coherence tomography (3D‐OCT) has attracted attention for visualising complex structures in the biomedical field. In this reported work, a high‐speed 3D‐OCT system is developed, which is based on a high‐speed swept light source and a Mach‐Zehnder interferometer with a high‐speed photodetector. The light source, incorporating a KTa 1– x Nb x O 3 electro‐optic deflector, operates at a repetition rate of 200 kHz and enables high‐speed data acquisition. As a preliminary study, images of a strawberry's surface have been obtained, two‐ and three‐dimensionally. The 3D‐OCT system has potential for the construction of a four‐dimensional OCT image to dynamically display 3D‐OCT images.
