A Low-Cost and Highly-Sensitive Method for Waste Oil DetectionA research team led by Prof. TANG Jie from Xi'an Institute of Optics and Precision Mechanics proposed a method of discharge-assisted laser-induced breakdown spectroscopy combined with filter paper sampling (DA-LIBS-FPS) to detect the hazardous components in... Laser-induced breakdown spectroscopy (LIBS) is a promising trace detection technique to realize the rapid, real-time, and on-line analysis. However, LIBS faces unfavorable factors such as large signal fluctuations, low spectral intensity, poor signal-to-noi...Jan 04, 2024 -
Spaceborne Optical Switching Technology Completes On-orbit VerificationThe prototype of spaceborne optical switching system has successfully been launched and conducted in-orbit validation with the 'Xiguang-1' satellite, which is independently research and developed by Xi'an Institute of Optics and Precision Mechanics (XIOPM) ... All-optical switching technology breaks through traditional technological barriers, providing faster switching speed, larger bandwidth, higher reliability and security. It allows for direct processing optical signals in the optical domain, without the need ...Nov 14, 2023 -
How to realize achromatic metalens with varifocal performance?The recently proposed broadband achromatic metalens (BAM) have been considered as a promising method to correct chromatic aberration in broadband imaging systems. However, these BAMs are limited to a fixed functionality that severely hinders their potential... Metalens, one of the most prominent applications of metasurface, has demonstrated the promising abilities to replace traditional lens. By manipulating the phase distribution of metalens composed of appropriately arranged meta-atoms, the wavefront of inciden...May 16, 2023 -
