Advanced Science, EarlyView.A speckle correlation centroid localization method (SCCLM) is proposed for non‐invasive tracking of an arbitrary deformable object through scattering media and around corners, requiring no prior information. Its effectiveness is demonstrated not only in tracking hidden objects beyond the memory effect region but also in following objects undergoing ...

Advanced Science, EarlyView.A steric‐hindrance molecular engineering strategy uses dimethyl maleate (DMM) to convert poly(1,4‐butanediol) bis(4‐aminobenzoate) (PBDAB) into a precursor with reduced reactivity via Michael addition, thereby retarding the curing process to form a transparent, ultraflexible, and self‐healable secondary‑amine polyurea (PuSA) with a crosslinked network.

Acoustic reflected wavefront modulation based on Helmholtz resonator array
AIP Advances, 2022 In this work, a Helmholtz resonator (HR) with a subwavelength scale is proposed to modulate the acoustic wavefront in multiple manners. The phase response of the reflection wave can be continuously adjusted by altering the height of the cavity.

Time-domain wavefront shaping for secure communication
, 2020 Recently, we applied wavefront shaping techniques to implement quantum-secure readout of a physical unclonable key for authentication [1]. Unfortunately, spatial wavefront shaping is unsuitable for long-distance use. We therefore propose to use wavefront

Multiple feedback based wavefront shaping method to retrieve hidden signal
, 2022 We present an optical wavefront shaping approach that allows tracking and localization of signal hidden inside or behind a scattering medium. The method combines traditional feedback based wavefront shaping together with a switch function, controlled by ...

Ultra‐Wide‐Field Noninvasive Imaging Through Scattering Media Via Physics‐Guided Deep Learning
Advanced Science, EarlyView.We propose a physics‐guided adaptive dual‐domain learning method for ultra‐wide‐field noninvasive imaging through scattering media, namely UNI‐Net. Our method not only reduces the requirement for real experimental data by an order of magnitude but also enables clear imaging of complex scenes with an ultra‐large field of view, which is 164 times the OME
