Joint R&D by CamOptics, Beihang University, and the Institute of Extremely Weak Magnetic Fields Enables a Dynamic 3D Holographic Display with Ultra-High Contrast, Fast Response, and Continuous Tunability
Author:
Recently, the teams led by Jin Li from Beihang University, Xiaoxun Li from the Hangzhou Institute of Extremely Weak Magnetic Field Laboratory, and Kun Li from CamOptics, Ltd., have experimentally demonstrated for the first time a cascaded device combining polymer-dispersed liquid crystal (PDLC) and a broadband metasurface, achieving a dynamic three-dimensional (3D) holographic display with ultra-high contrast, fast response, and continuous adjustment. The PDLC droplets are electrically scanned by a high-speed dynamic control system, thereby modulating the scattering state of the incident light. Based on the self-addressing, fast-response, and multi-channel PDLC-metasurface device, dynamic holographic effects of monochrome holographic image switching and color-changing holographic displays were achieved, exhibiting broadband, low crosstalk, and high contrast. The authors' approach provides a novel perspective for the research of dynamic metasurfaces.
The research findings were published on December 24, 2024, in Microsystems & Nano-engineering under the title “Dynamic 3D metasurface holography via cascaded polymer dispersed liquid crystal”.
Abstract：
Metasurface with natural static structure limits the development of dynamic metasurface holographic display with rapid response and broadband. Currently, liquid crystal (LC) was integrated onto the metasurface to convert the passive metasuface into an active one. But, majority of LC-assisted active metasurfaces often exhibit trade-offs among degree of freedom (DoF, typically less than 2), information capacity, response speed, and crosstalk. Herein, at first time, we experimentally demonstrate a cascaded device with polymer dispersed liquid crystal (PDLC) and broadband metasurface, enabling dynamic three-dimensional (3D) holographic display with ultra-high contrast, rapid response and continuous regulation. The PDLC droplets enable modulation of scattering state of incident light by high-speed dynamic control system for electric scanning. Based on self-addressing, rapid response and multi-channel PDLC-metasurface device, the dynamic holographic effect of monochrome holographic images switching and color changing holographic display with broadband, low-crosstalk and high contrast, has been achieved. Our approach offers a novel perspective on dynamic metasurface.
