Stimuli‐responsive circularly polarized luminescent materials have broad application prospects in fields such as information encryption and anti‐counterfeiting, chiral optoelectronic devices and so on. In this study, 0D antimony‐based halides enantiomer R ‐DMSO and S ‐DMSO with bright yellow fluorescence, were successfully prepared using R/S ‐3‐aminoquinine cyclic ammonium as the organic cation. Enantiomer R ‐DMSO and S ‐DMSO exhibit interesting self‐trapped excitons (STEs) emission and fascinating circular dichroism (CD) with photoluminescence quantum yield (PLQY) approaching 100%. In addition, enantiomer R ‐DMSO and S ‐DMSO exhibited significant circularly polarized luminescence (CPL) signals, with a measured luminescence dissymmetry factor () of approximately ±7.61 × 10 −4 . By immersing R/S ‐HCl in DMSO, it can be transformed into yellow fluorescence, its CPL signals are almost identical to R/S ‐DMSO. After heating at 110°C for 1 h in a vacuum oven, it is transformed back into R/S ‐HCl, this process achieves reversible switching of CPL signals. By utilizing this property, relevant applications of dual information encryption and anti‐counterfeiting have been carried out. In addition, UV pumped circularly polarized light‐emitting diode (CP‐LED) devices based on enantiomer R ‐DMSO and S ‐DMSO exhibit excellent luminescence performance, with of approximately 3.68 × 10 −3 and −3.85 × 10 −3 . This study provides a new approach for the development of stimuli‐responsive functional chiral antimony‐based hybrid halides.

A simultaneous ToF/FMCW LiDAR architecture is demonstrated using a dual-mode light source that alternately generates optical pulses and frequency-chirped light within a single acquisition. By combining time-domain ToF and coherent FMCW ranging, the system achieves high-resolution ranging and velocity sensing while extending the measurable range beyond the Nyquist-limited FMCW range under constrained electrical bandwidth.

Real‐time ranging of thermal targets holds critical importance for defense, surveillance, and autonomous navigation, yet remains fundamentally constrained by the inherently low texture of thermal imagery. A metasurface‐Transformer architecture is presented to enable monocular four‐dimensional (4D) thermal light‐field imaging and subsequent ranging. The optical front end uses an all‐silicon metasurface microlens array directly integrated into a commercial thermal camera module, forming a compact light‐field imager. The computational back end, a thermal disparity transformer (TDiT), resolves sub‐pixel disparities from the texture‐scarce thermal light‐field through dedicated pre‐processing and Transformer‐based inference. The system achieves centimeter‐scale accuracy, with a mean ranging error of 1.87% at 25 ms per frame, enabling real‐time dynamic ranging of moving thermal targets. By combining metasurface‐enabled light‐field capture with high‐precision disparity estimation, this work provides a promising approach for effective, real‐time perception in texture‐scarce thermal environments.
