Wide-angle color holographic near eye display with full bandwidth frequency multiplexing.

ABSTRACT: Wide-angle holographic near-eye displays (HNEDs) face challenges in achieving high frame rates, full-color, high-resolution images, and shallow depth of field. Existing full-color methods either rely on time multiplexing or suffer from reduced image resolution due to the applied filtering of the available spatial bandwidth of the light modulator. To address these limitations, we propose a non-pupil HNED system that reconstructs large 3D full-color scenes from a single hologram using RGB LED illumination. The non-pupil architecture allows employing an incoherent LED source, which offers reduced speckle noise and high imaging resolution. This is, to our knowledge, the first wide-angle 3D color holographic display to use a single spatial light modulator (SLM) at full frame rate. Our system is
