COMPACT HEAD-MOUNTED EYE MOVEMENT TRACKING DISPLAY Russian patent published in 2017 - IPC G02B27/01 H04N5/00 

FIELD: physics.

SUBSTANCE: head-mounted eye movement tracking display contains a microdisplay for forming a user-viewing image, having an optical display path and an exit pupil associated therewith, an image sensor for tracking the eye movement. Moreover, the optical display device has a surface closest to the microdisplay and the image sensor, and the optical display device is located relative to the microdisplay and the image sensor so that the optical display paths and the image sensor are on the respective different parts of the surface closest to the microdisplay. Herewith the optical display path and the optical sensor path, each, have respective optical axes passing through the optical display device and the image sensor, respectively, wherein these optical axes are inclined relative to each other in the second plane.

EFFECT: ensuring the creation of the head-mounted eye tracking display without significant increasing of weight and volume.
