A high-speed functional fundus three-dimensional detection system based on near-infrared light, comprising a supercontinuum laser module (1), a laser scanning module (2), a dispersion focusing module (3), a non-de-scanning spectrum detection module (4), and a de-scanning spectrum detection module (5). A near-infrared band of a supercontinuum laser is used to illuminate the fundus, which can not only reduce the influence of the visible light to human eyes, but also improve the focusing effect and the imaging resolution by means of the high spatial coherence of the supercontinuum laser. In the processes of fundus depth information detection and data processing, the de-scanning spectrum detection module (5) and the dispersion focusing module (3) are used to calculate depth data of the fundus. In the fundus oxygen saturation measurement and data processing, a large numerical aperture two-dimensional fiber bundle terminal in the non-de-scanning spectrum detection module (4) is used to improve the spectrum detection efficiency, and thus a reflection spectrum type oxygen saturation method is used to calculate the oxygen saturation of each part of the fundus.
