Abstract

One of the most critical components of AR glasses is the “glass” itself - the combiner. Ultimately, the combiner has to function as a classical ophthalmic lens, i.e. fit each user well - physically and aesthetically - and provide custom corrective function. It should ideally look entirely transparent to the user as well as to those looking into the user’s eyes while creating no unwanted artifacts like rainbows or glows. On top of that, it has to deliver high-quality, bright, and power-efficient digital 3D imagery only to the user’s eyes while providing identical focus cues and prescription correction to the digital content as to the reality. Of course, it must be inexpensive, too. CREAL has developed and demonstrated its light-field HOE combiner that conceptually approaches all the above requirements. This talk will introduce how.
