Professor Xue's group performs research in biomedical optical imaging, atomic spectroscopy and related laser physics.
a) Studies in biomedical optic focus on optical imaging using optical coherence tomography (OCT) and optical Doppler tomography (ODT). Research includes development of imaging technologies and clinical applications. Technology development includes high resolution, spectroscopic imaging, development of imaging devices such as catheter or endoscope based systems. Biomedical studies include clinical investigations of ophthalmic applications in collaboration with the Tong Reng Hospital. Studies of optical biopsy in internal medicine in collaboration with investigators at the Sino-Japan Friendship Hospital. In addition, the integration of OCT with other technologies such as multi-photon excitation fluorescence confocal microscopy is also studied to obtain more information of bio-tissue and broaden the application field. The research subjects includes:
1、Photon migration in turbid medium or bio-tissue
2、Optical coherence tomography and Optical Doppler tomography
3、Laser coherent remote sensing and imaging
4、Microscopic and spectral imaging
5、Fiber optics and MEMS
b) Studies in atomic spectroscopy focus on the high Rydberg states of complex atom and its laser spectroscopy by time of flight (TOF) technique. Electron correlation is specially studied to understand dynamics of interaction of electron and nucleus in highly excited atoms and ions. Laser atom cooling technology is utilized to obtain ultra-cold atoms and initiate the studies of highly excited states of ultra-cold atoms and the interactions between the cold atoms. The research subjects includes:
1、Laser-atom interaction
2、Dynamics of highly excited states of atoms
3、Behaviors of ultra-cold atom
4、Study of perturbation states of complex atoms and ions
5、Correlation of atom, molecule and nanometer-scale materials
