Abstract
Examples of an imaging system for use with a head mounted display (HMD) are disclosed. The imaging system can include a forward-facing imaging camera and a surface of a display of the HMD can include an off-axis diffractive optical element (DOE) or hot mirror configured to reflect light to the imaging camera. The DOE or hot mirror can be segmented. The imaging system can be used for eye tracking, biometric identification, multiscopic reconstruction of the three-dimensional shape of the eye, etc.

-20. (canceled)
A imaging system comprising:
- an optical element configured to be positioned in front of an eye of a user;
- a forward-facing imager;
- a virtual backward-facing imager;
- and
- a reflective element,
- wherein the forward-facing imager is configured to capture light reflected by the reflective element, and the forward-facing imager and the virtual backward-facing imager are equidistant from the optical element.
