Abstract

A novel waveguide near to eye display (WGNED), with new in-coupling and propagation subsystems, is proposed for the first time, to our knowledge, to enlarge the vertical field-of-view (FOV) and the vertical size of the eye box. Two waveguides are stacked—one is for in-coupling and the other for out-coupling. A freeform prism is used to correct the aberrations. These components are combined to form the WGNED. We have simulated such a system; as a result, we show that it achieves a FOV of 30°horizontal(H)×60°vertical(V) and an eye box of about 15mm(H)×12mm(V). The modulation transfer function of the system is larger than 0.3 at 33lp/mm and the distortion is smaller than 5%.
