About

Hongjing Cao is a leading researcher in bio-inspired optics and micro-optical systems, with a primary focus on developing advanced 3D perception technologies for embodied intelligence. Her most notable contribution is the design of a planar compound eye microsystem that achieves high-precision 3D panoramic vision, drawing inspiration from the visual architecture of insects. This work, published in 2024 and already garnering 29 citations, addresses a critical challenge in robotics and autonomous systems: enabling compact, wide-field depth sensing without the bulk of traditional binocular or LiDAR setups. By mimicking the compound eye’s structure, Cao’s system offers a lightweight, scalable alternative for real-time spatial awareness, with potential applications in drones, micro-robots, and augmented reality. Her research bridges fundamental optics and practical engineering, demonstrating how nature’s solutions can drive innovation in machine perception. With her work gaining rapid traction, Cao is establishing herself as a key figure in the next generation of vision systems for intelligent machines.
