Researchers from the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP), Chinese Academy of Sciences, together with collaborators at Changchun University of Science and Technology, reported a hardware-based optimization strategy for intersatellite laser links in Optics Communications. The paper introduced a signal processing architecture combining complex rotation algorithms with error correction coding, effectively solving the interference problem between data transmission and precision ranging in space gravitational wave detection.
Researchers from the Changchun Institute of Optics, Fine Mechanics and Physics , Chinese Academy of Sciences, together with collaborators at Changchun University of Science and Technology, reported a key noise evaluation strategy for space-based interferometry in Symmetry-Basel. The paper introduced a comprehensive noise model and a symmetric differential circuit design, significantly reducing the phase measurement error in gravitational wave detection systems.
Scientists reported a comprehensive modeling strategy for the China Survey Space Telescope (CSST) in Research in Astronomy and Astrophysics. The paper introduced an end-to-end simulation framework that integrates static and dynamic error models, realizing accurate prediction of the telescope's optical performance under in-orbit conditions.
Researchers from the Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, together with collaborators at the University of Chinese Academy of Sciences and NIMTE, reported a robust speed-control strategy for permanent magnet synchronous motors (PMSMs) in IEEE Transactions on Power Electronics. The paper introduced a new sliding-mode reaching law (NSMRL) and a variable-parameter generalized super-twisting observer (VGSTO), forming an improved sliding-mode controller (ISMC) that enhanced transient response and disturbance rejection while suppressing chattering.
Researchers from the Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, report self-powered far-UVC photodetectors based on cubic-phase MgZnO (c-MgZnO) in ACS Applied Materials & Interfaces. The team realized two device types—a Schottky junction and a PIN heterojunction—that operated at zero bias with nanosecond response and stable performance at high temperature.
Researchers from the School of Electronics and Information Engineering at Hebei University of Technology and the State Key Laboratory of Luminescence Science and Technology at the Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences, report how to balance defect passivation with the quantum confinement effect (QCE) in ligand-free blue perovskite emitters. The study appears in Laser & Photonics Reviews and shows that selecting weakly coordinating additives enables efficient, spectrally stable, sky-blue CsPbBr₃ light-emitting devices while avoiding the redshift that often accompanies strong passivation chemistry.
