Summary:The utility model discloses an eye movement tracking system which comprises two projectors, two cameras and a controller. The two projectors are arranged corresponding to the two human eyes respectively and comprise substrates, light sources and diffractive optical elements, the light sources are arranged on the substrates and used for projecting light used for irradiating the corresponding human eyes and serving as reference positions, and the diffractive optical elements are used for diffracting the light projected by the light sources to form projection patterns at the human eyes. The diffractive optical element is located between the light source and the human eye. The two cameras are arranged corresponding to the two human eyes respectively and used for shooting images of the corresponding human eyes, and the images of the human eyes comprise images of the human eyes and images of projection patterns formed at the human eyes. The controller is electrically connected to the camera and the projector, and t
