Abstract
A wide field-of-view (FOV), high-resolution, and compact optical engine for augmented reality projection display is highly anticipated, though trade-offs exist among them. Diffractive image steering by a digital micromirror device facilitates two-dimensional FOV expansion without compromising image resolution while decoupling the tradeoff. A fivefold increase in the horizontal FOV and a twofold increase in the vertical FOV demonstrated that results in an expanded FOV of 30(H)×31(V) degrees image generated from a limited pixel count of the spatial light modulator (SLM) that preserves an angular resolution of 32pixels/deg.
