Recently, Prof. LIU Kewei’s team from the Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) of the Chinese Academy of Sciences (CAS) proposed to enhance the performance of p-Si/n-ZnGa2O4 heterojunction solar-blind UV photodetector through interface regulation. The results were published on the Journal of Materials Chemistry C. Owing to the excellent solar-blind UV photoelectric
In a study published in Signal Processing, Dr. MA Mingyang from Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP) of Chinese Academy of Sciences (CAS) and his collaborators found that radiation intensity can be used to address the drawback of Gaussian mixture probability hypothesis density (GM-PHD) filter in close target tracking.
Temperature is one of the basic physical quantities. Nowadays, emerging industries are developing rapidly, and it is difficult for existing commercial thermometers to meet the difficult and high-precision requirements of some special applications. Instead, optical temperature sensing solution based on luminescent materials has demonstrated unique advantages in temperature detection.
In recent years, the variance-based method of global sensitivity analysis (GSA) has been increasingly and widely used in various engineering applications, particularly spacecraft thermal design optimization. However, such estimations require many samples to ensure sufficient accuracy, which makes GSA expensive to perform when modeling is difficult. Moreover, multimodal or highly skewed output distribu
Recently, the liquid crystal adaptive optics research team from Changchun Institute of Optics, Fine Mechanics and Physics (CIOMP), Chinese Academy of Sciences (CAS) has built a high-density integrated beam array generation system using Liquid Crystal Optical Phased Array (LCOPA). The number of sub-beams in the integrated beam array is 40×40, and the average pointing accuracy is less than 20μrad. This study is published on Optics Communications.
In a study published in Nanomaterials, Dr. ZHAO Zhen from Changchun Institute of Optic, Fine Mechanics and Physics (CIOMP) of Chinese Academy of Sciences (CAS), and his collaborators found that single uniform nanowire can be fabricated by femtosecond laser with the help of a groove.
