Abstract

Systems and methods for eye tracking are disclosed. The system may emit, by a digital micro-mirror device(s) (DMD), light, including binary images or grayscale images, onto an eye(s) of a user. The system may determine, by single pixel detectors, a reflection of the light from the eye(s). The system may determine, by a first single pixel detector, a first signal associated with the reflection of the light from a retina of the eye(s). The system may determine, by a second single pixel detector, a second signal associated with the reflection of light from the retina of the eye(s). The system may perform, by the DMD(s), a transformation on the first and second signals to determine a grayscale image(s) of the retina. The system may determine, by the DMD(s), a 3D shape(s) of the retina based on performing a 3D reconstruction(s) associated with pixels of the grayscale image(s) of the retina.
