Time‐Stretched Interferometric LiDAR with Dispersive Wavenumber‐to‐Time Range Encoding
Laser &Photonics Reviews, Volume 20, Issue 5, 6 March 2026.We present a time‐stretched interferometric LiDAR that directly encodes distance into time‐domain interference signals. Operating at 5 MHz with only millimeter‐level coherence length, the system measures up to 12 m with centimeter precision and resolution, achieving high‐speed 3D imaging and dynamic target detection without FFT processing or long ...

Multi‐Soliton Microcombs Enable Ultrafast Nanometric‐Precision Ranging and Photon‐Level Detection
Advanced Science, Volume 13, Issue 12, 27 February 2026.Our work first demonstrates dual‐multi‐soliton ranging and confirms its multifunctional capability. The method achieves ultrafast and nanometric‐precision measurement. For practical applications, we further extend the multi‐soliton states to photon‐level ranging.

Quarterly Journal of the Royal Meteorological Society, Volume 152, Issue 774, January 2026 Part A.We use active remote sensing from a ship during the EUREC4$$ {\mathrm{EUREC}}^4 $$A campaign to characterize the environment before, during, and after precipitation in shallow convection. (1) Shallow clouds barely precipitate (only virga). Congestus clouds generate precipitation, occurring less often in the afternoon but with higher cloud fractions. (2)
