Abstract: Angular sensors that may be used in eye-tracking systems are disclosed. An eye-tracking system may include a plurality of light sources to emit illumination light and a plurality of angular light sensors to receive returning light that is the illumination light reflecting from an eyebox region. The angular light sensors may output angular signals representing an angle of incidence of the returning light.
