Core research focuses on computational optical imaging technology and spectral imaging system engineering, with key efforts on the design, development, technical optimization and aerospace engineering application of space-borne/airborne spectral imaging equipment. Research interests cover coded aperture spectral imaging, hyperspectral/multispectral imager design, high-precision spectral calibration, radiometric measurement, and spectral data acquisition/processing. Special attention is paid to the miniaturization and integration of spectral imaging devices, including lensless multispectral imaging, sparse target real-time spectral detection, and rapid spectral calibration technology. Also engaged in the research of Fourier transform spectroscopy, interferometric super-resolution spectral imaging and polarized hyperspectral imaging, and the application of spectral remote sensing technology in near-space detection, black soil parameter calibration and space-borne remote sensing missions. Committed to solving key technical problems in aerospace spectral imaging equipment R&D and promoting the engineering transformation of spectral imaging technology.
