Eye imaging in head worn computing
First Claim
Patent Images
1. An eye-imaging system for a head-worn display, comprising:
- a display adapted to produce image light, the display positioned to project the image light in-line with transfer optics adapted to present the image light to an eye of a user;
an IR light source positioned to illuminate the eye with an IR light; and
a camera positioned to capture eye-image light that originates as a reflection of the IR light off of the eye, wherein the eye-image light travels in-line with an optical path traveled by the image light in the transfer optics and wherein the eye-image light follows an optical path that does not involve the display.
