We are Computational Optics Imaging and Sensing (COIS) Group in Prof. Fan Wang's Lab in 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.

We are developing nover microscopy methods to overcome the current limitations of traditional solutions, with a multidisciplinary approach. Several keywords are super-resolution Imaging, deep-tissue imaging, structured illumination, near-infrared, wavefront shaping, adaptive optics, unconversion nanoprobes and so on.

The single-pixel imaging technique produces images without the need for a 2D detector, making use of structured detection or illumination of the object to computationally derive an image. We are developing the novel single-pixel imaging methods for imaging through scattering medium, hyperspectral imaging,edge imaging, dark-field imaging, lifetime imaging and so on.
Papers: ArXiv preprint (2023)
In this direction, we try to delelop ultra-compacted lensless imaging systems for high-dimensional imaging to recover the depth, spectral, polarization, temporal and phase (XYZλθτφ) information of targets. A example of such devices is our Diffuser-based camera.
Papers: ArXiv preprint (2024) |
As one of the recently rised research topic, computational spectrometer offers high spectral measurement performance but with much smaller size or footprint than a traditional spectrometer. We are developing computational spectrometer with easy-to-prepare and low-cost implementation.
Papers: Optica
We are developing the single-multimode fiber or fiber-bundle based endoscopes for high-resolution and hyper-spectral imaging.
