Original Abstract Submitted
a system is provided. the system includes a light source configured to emit a infrared (“ir”) light for illuminating an object. the system also includes a waveguide imaging assembly including a waveguide, an in-coupling element disposed at a first portion of the waveguide, an out-coupling element disposed at a second portion of the waveguide, and an optical sensor disposed facing the out-coupling element. the in-coupling element is configured to couple the ir light reflected by the object into the waveguide, the waveguide is configured to guide the ir light to propagate toward the out-coupling element through total internal reflection, and the out-coupling element is configured to couple the ir light out of the waveguide toward the optical sensor. the optical sensor is configured to generate a tracking signal of the object based on the ir light output from the waveguide.
