Abstract
We present a holographic multiplane near-eye display method based on Fresnel holography and amplitude-only wavefront modulation. Our method can create multiple focal images across a wide depth range while maintaining a high resolution (1080P) and refresh rate (60 Hz). To suppress the DC and conjugation signals inherent in amplitude-only wavefront modulation, we develop an optimization algorithm which completely separates primary diffracted light from DC and conjugation at a pre-defined intermediate plane. Spatial filtering at this plane leads to a dramatic increase in the image contrast. The experimental results demonstrate our approach can create continuous focus cues in complex 3D scenes.
