我国芯片研制获重大突破！

Core Viewpoint - The article highlights a significant breakthrough in the field of smart photonics by a research team led by Professor Fang Lu from Tsinghua University, who developed the world's first sub-angstrom snapshot spectral imaging chip, marking a new milestone in high-precision imaging measurement in China [1][3]. Group 1: Technological Breakthrough - The newly developed chip measures approximately 2 cm × 2 cm × 0.5 cm and can achieve sub-angstrom spectral resolution and tens of millions of pixels spatial resolution across a wide spectral range of 400-1000 nanometers [3]. - This chip allows for simultaneous acquisition of full spectral and spatial information in a single snapshot, enhancing the snapshot spectral imaging capability by two orders of magnitude, thus overcoming the long-standing bottleneck between spectral resolution and imaging throughput [3]. Group 2: Innovation and Applications - The research team innovatively proposed a reconfigurable computational optical imaging architecture based on smart photonics principles, transforming traditional physical spectral splitting limitations into photon modulation and computational reconstruction processes [3]. - The "Yuheng" chip developed by the team addresses challenges related to resolution, efficiency, and integration in spectral imaging systems, with potential applications in machine intelligence, airborne remote sensing, and astronomical observation [3]. - For instance, in astronomical observations, the "Yuheng" chip can capture the complete spectrum of nearly 10,000 stars per second, potentially reducing the survey period for the spectra of the hundreds of billions of stars in the Milky Way from thousands of years to under ten years [3].
