Biometric system for xr head-mounted display

Abstract

An eye/iris biometric system for an extended reality (XR) head-mounted display is provided. The system includes an eye/iris imaging optical unit, a display imaging optical unit, a near-infrared illumination optical unit, and an eye/iris image imaging control unit mounted in the head-mounted display. The eye/iris imaging optical unit is used for physical imaging of near-infrared incident light of an eye/iris. For the display imaging optical unit, an image display source image is emitted to the human eye for image projecting by optical path imaging of a display imaging assembly. The display imaging assembly controls an illumination radiation angle and an illumination angle of emergence of a light-emitting diode (LED) by an angle optical assembly to generate related near-infrared light emitted to the human eye. The eye/iris image imaging control unit controls the eye/iris imaging optical unit and the near-infrared illumination optical unit to generate an eye/iris image.
