Abstract Computer-generated holography is a promising technique that modulates user-defined wavefronts with digital holograms. Computing appropriate holograms with faithful reconstructions is not only a problem closely related to the fundamental basi

Dielectric metasurfaces with tunable functions are increasingly appealing to both the academia and industrial communities. Among the many tuning mechanisms reported so far, metasurface immersed in liquid crystal (LC) stands out as one of the most via

Abstract Here, we propose and demonstrate a modular holographic display system that allows seamless spatial tiling of multiple coarse integral holographic (CIH) displays called “holobricks”. A holobrick is a self-contained CIH module enclosing a

Mercury exposure constitutes an acute risk to human health and the environment. Driven by the requirement to monitor trace-level mercury, we report a highly sensitive mercury(II) DNA sensor enhanced by silver(I) activation, followed by mercury(II)-sp

In this paper, we propose and experimentally demonstrate a parallel coding and two-beam combining approach for the simultaneous implementation of dynamically generating holographic patterns at their arbitrary linear polarization states. Two orthogona

Holographic generation of beam spot array with high uniformity have been extensively investigated while existing methods cannot combine high quality and tunability. This paper demonstrated a method to generate beam spot array by using phase-only liqu

A fast hologram calculation approach is proposed to reduce computational load by avoiding the recalculation of redundancy information. In the proposed method, the hologram is divided into several sub‐holograms that record and reconstruct different

A deep learning model was built to optimize the phase flicker performance for given pulse width modulation (PWM) driving patterns of a liquid crystal on silicon (LCOS) device. 10-bit phase modulation was physically realized with a phase flicker of 0.
