Metasurface Technique Enables Advanced Holography Applications
WUHAN, China, Dec. 28, 2023 — Computer-generated holography (CGH) represents a cutting-edge technology that employs computer algorithms to dynamically reconstruct virtual objects. Despite its broad application spectrum, contemporary techniques for CGH rely on projection devices like spatial light modulators (SLMs) and digital micromirror devices (DMDs). These devices inherently face limitations in display capabilities, often resulting in narrow field-of-view and multilevel diffraction in projected images. Recently,
