An eye-imaging system for a head-worn computer with a see-through display, comprising:
- a camera positioned in the head-worn computer with the see-through display, wherein the camera is further positioned to capture an image of an eye of a user wearing the head-worn computer;
- an IR light source positioned in the head-worn computer such that it irradiates the eye of the user with IR light;
- a hot mirror comprising a partially reflective partially transmissive surface adapted to reflect IR light and transmit visible light positioned in the head-worn computer such that image content light is transmitted through the hot mirror to the eye of the user and IR light reflected from the eye of the user is reflected by the hot mirror towards the camera;
- and
- the camera adapted to capture the IR light as the reflections from the eye of the user.
