I am interested in computational imaging with joint optimization of optics and algorithms. I am currently working on developing computational imaging based on the metasurface for interesting applications, such as hyperspectial imaging and holographic display, etc.

We introduce a new paradigm for the hybrid metalens design based on differentiable ray tracing. Through joint optimization of the phase distribution of the metalens and refractive lens parameters, our system achieves achromatic performance within the broad spectral range of 440-700 nm, with an aperture of 1 cm and an f-number of 1.4.

We introduce a comprehensive end-to-end computational spectral imaging system based on a polarization multiplexed metalens. Through jointly optimizing the front-end metalens and the back-end neural network, this work achieves high-fidelity computational spectral imaging.

We propose a compact and portable snapshot hyperspectral imaging system, which utilizes a metasurface and achieves joint optimization of hardware and recovery algorithm.

We propose a novel full-color computational imaging system jointly optimizing the metalens and CGH for advanced imaging capabilities.

We propose a metalens-based 3D holographic near-eye display system.
