Abstract:One head-mounted display visual system for computer entertainment and three-dimensional display of virtual-reality was achieved, which consists of a hybrid refractive-diffractive eyepiece and a relay reflector. It can be used in micro-display of liquid crystal on silicon (LCOS) diagonal of 18 mm. The whole system has better performance, with 60° field of view, 10 mm exit pupil, 23 mm eye relief, and reduces weight and size.
Keywords:refractive-diffractive  micro-display  relay reflector
