AI-Powered Compressed High-Speed ImagingResearchers from the Xi’an Institute of Optics and Precision Mechanics of the Chinese Academy of Sciences have developed a multi-prior physics-enhanced neural network (mPEN)，which can overcome the spatial distortion and reconstruction artifacts inherent i... Recently, a research team from the Xi’an Institute of Optics and Precision Mechanics (XIOPM) of the Chinese Academy of Sciences (CAS), in collaboration with the Institute National de la Recherche Scientifique (INRS) in Canada and Northwest University, dev...Jan 21, 2026 -
New Progress in Cross-domain Few-Shot Hyperspectral Image ClassificationResearchers from the Xi’an Institute of Optics and Precision Mechanics of the Chinese Academy of Sciences have developed a cross-domain few-shot hyperspectral classification framework named SpectralDINO. By integrating DINOv2 with parameter-efficient tunin... Hyperspectral imaging captures detailed material information across hundreds of spectral bands; however, its real-world use has been limited by the scarcity of labeled data and sensor differences. In a study published in IEEE Transactions on Geoscience and ...Oct 17, 2025 -
Novel Framework for Interference Data Denoising and Baseline CorrectionResearchers from the Xi’an Institute of Optics and Precision Mechanics of Chinese Academy of Sciences have proposed a novel interference data denoising network (InDNet) ,which is able to simultaneously denoise and correct baselines in spatial heterodyne in... Spatial heterodyne Raman spectroscopy is a powerful tool for high-resolution spectral detection but is often hindered by weak signals, noise, and complex baselines caused by instrumental and environmental factors. It's difficult for traditional methods to h...Sep 24, 2025 -
Researchers Achieve Breakthrough in High-Energy Nanosecond Fiber LasersResearchers from the Chinese Academy of Sciences have developed a stimulated Brillouin scattering-based pulse shaping technique that boosts nanosecond fiber laser performance. By suppressing nonlinear effects, the method increases pulse energy to 0.58 mJ an... Nanosecond-pulsed fiber lasers are widely used in laser processing, remote sensing, and communications, but their performances are often limited by nonlinear effects such as four-wave mixing (FWM), which causes unstable sub-peaks and restricts further power...Sep 24, 2025 -
Researchers Develop Novel Miniaturized Lidar Technology Based on Cross Dual-microcombResearchers from the Xi’an Institute of Optics and Precision Mechanics of the Chinese Academy of Sciences have proposed a cross dual-microcomb precision ranging method that eliminates the asynchronous measurement errors prevalent in previous dual-comb sche... Optical frequency combs, as a time and frequency "ruler," have important applications in precision ranging. Conventional dual-comb ranging schemes utilize the optical Vernier effect to achieve long-distance measurements, and they typically require asynchron...Aug 19, 2025
