Core Insights - Tsinghua University's Professor Fang Lu's 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][2]. Group 1: Technological Breakthrough - The "Yuheng" chip addresses long-standing challenges in spectral imaging systems, specifically resolution, efficiency, and integration [2]. - The chip measures approximately 2 cm x 2 cm x 0.5 cm and operates within a wide spectral range of 400 to 1000 nanometers, achieving sub-angstrom spectral resolution and tens of millions of pixels in spatial resolution [1]. Group 2: Applications and Impact - The chip can be widely applied in fields such as machine intelligence, airborne remote sensing, and astronomical observation [2]. - For astronomical observations, the "Yuheng" 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 [2].
