Three-dimensional imaging of blood vessel using integral imaging technique is proposed. With a near infrared illumination, a finger is imaged through a lens array to capture elemental images. By processing the captured elemental images, the three-dimensional structure of the blood vessel is visualized. By extending the proposed method to double illumination of two near infrared wavelengths, it is expected to be able to capture not only the vessel structure but also three-dimensional distribution of oxygen saturation.
