Abstract
Aspects for a wearable augmented reality (AR) device are described herein. The aspects may include a light engine that includes a micro-display configured to emit light to form an image, a polarized beam splitter positioned horizontally adjacent to the micro-display and configured to receive the emitted light that passes through the polarized beam splitter, and one or more first imaging lenses positioned horizontally adjacent to the polarized beam splitter and configured to receive the diverged light. One of the first imaging lenses may include a reflection surface configured to reflect and converge the light. The polarized beam splitter may include a reflective coating configured to reflect the converged light. The aspects may further include an optical waveguide configured to guide the converged light to a predetermined position.
