Core Insights - Tsinghua University's electronic engineering team has developed the world's first sub-angstrom snapshot spectral imaging chip named "Yuheng," marking a significant advancement in intelligent photonics technology for high-precision imaging and measurement [1][3]. Group 1: Technological Breakthrough - The "Yuheng" chip measures approximately 2cm x 2cm x 0.5cm and operates within a wide spectral range of 400-1000 nanometers, achieving sub-angstrom spectral resolution and tens of millions of pixels spatial resolution in snapshot spectral imaging [3]. - The chip enhances snapshot spectral imaging resolution by two orders of magnitude, overcoming the long-standing bottleneck of balancing spectral resolution and imaging throughput [3]. Group 2: Applications and Impact - The "Yuheng" chip addresses challenges in resolution, efficiency, and integration in spectral imaging systems, with potential applications in machine intelligence, airborne remote sensing, and astronomical observation [4]. - For astronomical observations, the chip can capture the complete spectrum of nearly 10,000 stars per second, potentially reducing the survey period for the Milky Way's 100 billion stars from thousands of years to under ten years [4].
