Metasurface Holography
View through CrossRef
Holography has emerged as an ideal method for future immersive naked-eye displays, as it possesses the capability to record and reconstruct light wavefronts. However, traditional dynamic holographic devices always have some shortcomings, such as a small field of view, twin imaging, and multiple orders of diffraction, which bring many challenges to their practical application. Metasurfaces, composed of subwavelength unit cells, offer great potential in manipulating light fields and addressing these limitations. The latest research progress in the field of dynamic metasurface holography is summarized from the implementation methods to design strategies, mainly including the typical research works on dynamic meta-holography based on tunable metasurfaces and multiplexed metasurfaces. The emerging applications of dynamic meta-holography have the potential to accelerate the development of light field manipulation and micro−/nanofabrication in higher dimensions. This chapter also explores potential applications and development paths in the field.
