Researchers from the Changchun Institute of Optics, Fine Mechanics and Physics developed an intelligent error compensation method that significantly improves the accuracy of image-based linear displacement sensors. The research results were published in Measurement Science and Technology, providing a practical solution to a persistent challenge in precision measurement.
Recently, a research team from the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) developed a lightweight neural network called GSS-YOLO, providing a high-efficiency solution for this persistent challenge. The research results were published in Scientific Reports.
Researchers from the Changchun Institute of Optics, Fine Mechanics and Physics developed an improved Fizeau interferometry method to enhance the precision of measuring the coefficient of thermal expansion (CTE) in fused quartz. The study provides a more reliable approach for characterizing ultra-low expansion materials used in high-end optical and semiconductor systems.
Researchers from the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) of the Chinese Academy of Sciences, in collaboration with the Institute of Semiconductors of CAS, developed a double-layer silicon-based optical phased array (OPA) that significantly expands the scanning range of chip-scale LiDAR systems. The study was published in Scientific Reports.
Researchers from the Changchun Institute of Optics, Fine Mechanics and Physics of the Chinese Academy of Sciences, in collaboration with the National University of Singapore, have engineered a dynamic "laser needle" to solve a century-old problem in optical imaging.
Researchers from the Changchun Institute of Optics, Fine Mechanics and Physics of the Chinese Academy of Sciences proposed a novel method using a Shack-Hartmann wavefront sensor (SHWFS) combined with "extended sources" to accurately measure the atmospheric coherence length r. This research provides technical support for evaluating atmospheric turbulence in real-time, especially when observing targets that lack point-like light sources or are obscured by high background noise. The results were published in the journal Photonics.
