Abstract
Techniques for displaying holograms in wearable display devices are described. An image source projects holographic images sequentially in three primary colors into a waveguide, where the images are modulated in amplitude and phase in spatial light modulator (SLM). Depending on implementation, the image source may be located next to the waveguide or an end of optical fibers, where the optical fibers are provided to transport the holographic images near the waveguide for projection thereof into the waveguide.
