An illumination system includes a light source configured to emit a light beam in a first wavelength range, a beam splitter configured to split the light beam emitted by the light source into a plurality of light beams, a substrate configured to be placed in front of an eye of a user, and a plurality of reflectors located within the substrate. Each of the plurality of reflectors is configured to intercept one or more light beams from the plurality of light beams, reflect light in the one or more light beams from the plurality of light beams to the eye of the user, and transmit light in a second wavelength range different from the first wavelength range to the eye of the user. The substrate is transparent to both light in the first wavelength range and light in the second wavelength range."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Efficient eye illumination using reflection of structured light pattern for eye tracking","description":"Disclosed herein are techniques for eye illumination for eye position tracking.
