Abstract
The present disclosed subject matter relates to a display device for displaying an image to an eye, comprising a support mounting a light source and a mirror assembly. The light source is configured to emit a visible light beam carrying the image towards the mirror assembly, and the mirror assembly is configured to angularly oscillate and deflect the emitted visible light beam towards the eye. A light sensor is mounted on the support and configured to record return light received via said mirror assembly from the eye. The display device further comprises a processor connected to the light sensor and configured to detect a state of the eye from the recorded return light.
