Incoherent Structured Light Enabled Crosstalk‐Suppressed 3D Volumetric Display

ABSTRACT

Continuous‐depth holography enabled by structured light sheets has recently emerged as a promising paradigm in 3D holography, attracting increasing research interest due to its capability to provide enhanced depth perception in volumetric displays. However, continuous‐depth holography faces a fundamental limitation: it relies on densely packed, spatially coherent frozen waves to form the target pixels in 3D space. This requirement constrains further resolution enhancement, while its sensitivity to external perturbations often leads to distorted reconstructions. Herein, a crosstalk‐suppressed 3D volumetric display with incoherent structured light is proposed and demonstrated experimentally, realized through controlled tuning of the inter‐pixel coherence of frozen waves, termed inter‐pixel decoherence (IPDC) technique. Our experimental results reveal that reconstructed profiles using the IPDC technique achieve high‐quality, crosstalk‐suppressed, are largely free from inter‐pixel cross‐talk, and maintain strong robustness against turbulence in 2D and 3D scenes. This holographic technique offers a practical and effective pathway for the advancement of crosstalk‐suppressed 3D volumetric holography in realistic natural environments.
