Abstract
A virtual reality or augmented reality vision system including: a first emission module, emitting light in the visible range; a second emission module, emitting light in the infrared range; an infrared-sensitive photodetection module; and a micromirror array. Each micromirror is capable of assuming a first position and a second position. Each micromirror of the micromirror array is configured to, in its first position, receive light from the first emission module and reflect it along an axis of interest. Each micromirror of the micromirror array is configured to, in its second position, receive light from the second emission module and reflect it substantially along the axis of interest, and receive light propagating along the axis of interest and reflect it towards the photodetection module.
