Title: OPTICAL SYSTEM FOR NEAR-EYE DISPLAYS
Abstract:
An optical system and method are presented for use in a near-eye display device for projecting a virtual image. The optical system comprises: an optical unit defining a light guiding channel for guiding input light indicative of the virtual image through said channel and providing output light with a field of view, said output light having a predetermined non-uniform intensity profile across said field of view; and a masking optical element optically coupled to an output of said optical unit for output light passage through the masking optical element, said masking optical element having a spatially varying transmission profile across said element configured in accordance with said predetermined non-uniform intensity profile, to affect regions of relatively high light intensity within said intensity profile to thereby apply intensity modulation to light passing through the masking optical element to provide virtual image with improved light intensity uniformity.
