Abstract
An inkjet is used to fabricate an optical device having a varying refractive index. The inkjet deposits a first material having a first refractive index and a second material having a second refractive index in a pattern on a substrate. The first material and/or the second material are processed to form an optical device having a refractive index that varies in one or two dimensions. The optical device is used in a virtual-reality system or augmented-reality system to provide angular selectivity from display to a user's eye.
