On April 14, Cheng Yuan's research team from the School of Artificial Intelligence at Shanghai Jiao Tong University made a significant breakthrough in the realms of intelligent sensing and optoelectronic computing. Their latest research findings, published in the esteemed journal Nature Sensors, introduce the world's first-of-its-kind polarization sensing and computing device, dubbed 'XuanJian' PolarSight SPU. This groundbreaking innovation seamlessly integrates a polarization sensing array with the front end of an optical neural network, empowering the system to capture polarization information while concurrently executing front-end feature processing and computation. This technological leap forward provides a novel implementation pathway for universal intelligent sensing and computing systems across all scenarios, heralding a new era where visual sensors transcend mere information collection to embrace integrated intelligent sensing and processing.

Traditional visual systems predominantly rely on brightness, color, and spatial texture information. In stark contrast, 'XuanJian', by incorporating the polarization dimension, can unveil concealed optical information such as the surface structure and material properties of objects. This remarkable capability substantially enhances target recognition and feature extraction, particularly in scenarios characterized by low illumination and interference from complex materials. The research was a collaborative effort between Associate Professor Cheng Yuan from Shanghai Jiao Tong University and Professor Joonki Suh's team from the Korea Advanced Institute of Science and Technology. The integrated sensing and computing system has already found industrial applications in high-end manufacturing, robotics, and other fields, offering fresh architectural insights for next-generation optical computing systems and edge-side visual systems.
