Abstract:
Eye-tracked head-mounted displays are provide which, in one aspect, may utilize the same optics for eyetracking and image viewing, with a selected portion of the optics used for an eyetracking optical path and a selected portion of the display optics used for an image viewing optical path.

Claim (Index 1):
An eye-tracked head-mounted display for displaying an image to an exit pupil thereof for viewing by a user, comprising:\n a micro-display for generating the image to be viewed by the user, the micro-display having a display optical path extending from the microdisplay to the exit pupil; a freeform optical prism in optical communication with the micro-display along the display optical path between the prism and the exit pupil with the micro-display optically conjugate to the exit pupil, the prism having a selected surface closest to the micro-display; an illumination source disposed at a location to illuminate the selected surface of the freeform optical prism with optical radiation from the illumination source, the freeform optical prism configured to transmit the optical radiation therethrough from the selected surface to the exit pupil; and an eyetracking sensor having a sensor optical path associated therewith that extends through the freeform optical prism from the exit pupil to the sensor, the image sensor located proximate the selected surface of the freeform optical prism to receive optical radiation reflected from a user's eye positioned at the exit pupil and transmitted through the prism along the sensor optical path to the sensor, the sensor optically conjugate to the exit pupil across the prism.
