We are Computational Optics Imaging and Sensing (COIS) Group, collaborated with Prof. Fan Wang and A/Prof. Xiaolan Zhong (School of Physics), Prof. Zhaohua Yang (School of Instrumentation and Optoelectronics Engineering), and Prof. Ling-An Wu (Institute of Physics, Chinese Academy of Sciences), at Beihang University, Beijing, China. Our research interests are in designing algorithms based optical imaging, microscopy, and sensing systems, including Fluorescent Super-resolution Imaging, Single-pixel/Ghost imaging, Diffuser based Camera, Computational Spectrometer/Hyperspectral Imaging, Fiber Imaging, Wavefront Shaping, Scattering Imaging and Novel Imaging Methods. Innovation in these areas would finds applications in bio-medical, industrial and physical research, which often operates right at the limit of current technology.

Video-rate super-resolution imaging through biological tissue can visualize and track biomolecule interplays and transportations inside cellular organisms. In this project, we developed a photon upconversion scheme for wide-field super-resolution imaging through the biological transparent window, featured by near-infrared and low-irradiance nonlinear structured illumination, which is helpful for developing video-rate super-resolution deep imaging methods. Moreover, both the nonlinearity of the emission and the tunability of upconversion nanoparticles (UCNPs) in emission wavelength or lifetime allow us to design more flexible and enhanced super-resolution imaging methods.

Single-pixel imaging produces images without the need for a 2D detector, making use of structured detection or illumination of the object to computationally derive an image. It can offer alternatives to conventional imaging, both for applications in the visible, but also as a low-cost alternative in regimes such as x-ray or infrared. Additionally, single-pixel approaches help to inform high-performance imaging techniques, for example, 3D depth, time-resolved or multispectral imaging, in which CCD based systems would be complicated or expensive to implement. Now we are developing novel compact single-pixel detection systems for imaging through scattering medium and multi-spectral imaging.
We are an interdisciplinary group, made up of people from many different backgrounds.
