Advanced Science, EarlyView.A metasurface‐enabled helical wavefront fingerprint (MHWF) paradigm is proposed for quantitative and specific retrieval of a liquid medium's refractive index and extinction coefficient. The liquid's complex dielectric response governs the wavefront evolution of the metasurface‐generated focused vortex beam, forming a distinctive three‐dimensional ...

Advanced Science, EarlyView.Low‐dose electron holography is limited by shot noise, which buries weak phase signals. HoloDenoiser, a physics‐informed network that works simultaneously in the spatial and frequency domains, locates and protects the holographic sideband while suppressing noise in the hologram.

Three-dimensional spatiotemporal focusing of holographic patterns
Nature Communications, 2016 Three-dimensional computer-generated holography cannot be implemented with temporal focusing. Here, Hernandez et al. use two spatial light modulators to control transverse- and axial-target light distribution, generating spatiotemporally focused patterns
