Dr. Mingjia Shangguan joined Xiamen University’s College of Ocean and Earth Science in 2019 and has been a faculty member of the State Key Laboratory of Marine Environmental Science since then. He is now an associate professor in applied oceanic physics. He received his Ph.D. in quantum information in 2017 from the University of Science and Technology of China. In 2017 and 2018, he worked as a deputy chief engineer in Glory China Quantum Lidar Ltd. After achieving some breakthroughs, including the development of a single-photon lidar to monitor the city’s air pollution and wind field, he started to develop a gas mapping lidar by adopting superconducting nanowire single-photon technology in 2019.
Lidar is an active remote sensing system. Since the wavelength of the laser is shorter than the millimeter wave by four orders of magnitude, lidar can detect very fine particulates, such as aerosols and molecules in the atmosphere, as well as water molecules and particles in the ocean. Dr. Shangguan’s research focuses specifically on advanced lidar technologies for urgent needs in the area of scientific and meteorological research, and geographic mapping.
Dr. Shangguan has already developed nine types of lidar systems with diverse functions, including a direct-detection Doppler wind lidar that is regarded as a most potential approach to obtain the global wind data. By employing different platforms, lidar can detect oceanic and atmospheric parameters with different spatiotemporal resolutions. Those parameters include wind, aerosol density, temperature, depolarization ratio, cloud, visibility, PM 2.5, and the concentration of atmospheric gas.
With the development of single photon technologies, especially in superconducting technologies and microwave photonics, developing a compact multifunction lidar is possible and critical. Dr. Shangguan developed a dual-frequency wind lidar equipped with a superconducting nanowire single-photon detector, which realized the highest spatial resolution of 10 m in 2017. This work has been reported and complimented on by the Optical Society of America (OSA) and American Association for the Advancement Science (AAAS), which reported that “it features a greatly simplified optical setup that makes it robust and stable enough to use in harsh environments such as aboard aircraft or satellites”. Furthermore, the novel upconversion wind lidar improves the performance of wind detection by two orders of magnitude compared to the traditional lidar system. As it is compact and lightweight, upconversion lidar can be installed on a UAV platform for wide applications. This work has been followed by more than 20 institutes globally, including NASA, ESA, and Danmarks Tekniske Universitet.
Dr. Shangguan now extends his research interest from atmospheric science to oceanic science. His oceanic optics lab is dedicated to developing advanced lidar for the detection of marine biogeochemical parameters.
