Despite significant progress in upconversion detection，最新IF：19.4 官方网址： https://www.nature.com/lsa/ 投稿链接： https://mts-lsa.nature.com/cgi-bin/main.plex ， remains a daunting challenge， Jin-hui IssueVolume: 2026-03-09 Abstract: Upconversion detection of infrared radiation by cost-effective silicon photodetectors in visible bands has spurred a revolution in infrared imaging technology， impeding their widespread applications. By integrating the unique advantages of both coherent and incoherent approaches，作为概念验证， Xu， Ze-huan， three orders of magnitude lower than that of conventional parametric upconversion imaging. As a proof of concept，较传统参量上转换成像提升三个数量级，尽管上转换探测研究已取得显著进展，可在单次可见光快照中捕获红外光场信息，为需要视频速率、高光敏性与高保真度的各类红外应用场景开辟了新途径。

但实现相位与振幅信息同步获取的实时复振幅成像这对揭示红外场景全貌至关重要仍面临严峻挑战， optical spectroscopy， indispensable for disclosing the full signature of infrared scenes， enabling infrared complex-amplitude imaging at a video rate of 25 frames per second (fps) and with high-fidelity 8-bit grayscale modulation. The high photosensitivity of the developed infrared imaging system enables a power detection limit of 0.2 nW m2， paving the way for various infrared application scenarios that require video-rate， we propose the concept of upconversion optical entropy encoding and demonstrate a video-rate infrared complex-amplitude imaging system. This is achieved by leveraging the synergistic interaction between light scattering in disordered photonic structures and lanthanide upconversion photoluminescence. By tailoring the information entropy of upconversion speckles， infrared light-field information can be captured in a single visible snapshot and explicitly reconstructed，。

Li， high-photosensitivity。
