Bringing natural focus and defocus to holographic displays through neural rendering and physically constrained wavefront generation.

01 / The idea

Natural blur.
Consistent depth.

Sharp objects are only part of a convincing 3D image. Out-of-focus regions also need to behave naturally. Conventional coherent holographic models can introduce ringing and incorrect depth cues, especially around transparent or reflective surfaces.

Our framework combines layered RGB-D scene information, neural rendering, and phase prediction with explicit wave-optical propagation. It preserves multiple depth contributions and generates a physically consistent wavefront for phase-only holographic display.

Based on the published paper.

02 / The method

Rendering meets
wave optics.

  1. Represent the scene

    Layered RGB-D retains depth information behind transparent surfaces and within reflections.

  2. Infer the wavefront

    Neural rendering supplies amplitude information; phase prediction completes the complex field.

  3. Enforce propagation

    Explicit diffraction and phase-only encoding connect the inferred field to the display.

From simulation to experiment

The same Couch scene is shown as a reference focal sweep, a numerical reconstruction, and an optical capture. Each clip can be played independently.
