全球首款，亚埃米级快照光谱成像芯片问世

Core Viewpoint - Tsinghua University's research team has developed the world's first sub-angstrom snapshot spectral imaging chip, "Yuheng," marking a significant advancement in intelligent photonics technology for high-precision imaging and measurement [1][4]. Group 1: Technological Breakthrough - The "Yuheng" chip measures approximately 2 cm x 2 cm x 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]. - The chip enables simultaneous acquisition of full spectral and spatial information in a single snapshot, enhancing spectral imaging resolution by two orders of magnitude [3]. Group 2: Applications and Impact - The "Yuheng" chip addresses challenges in spectral imaging systems regarding resolution, efficiency, and integration, making it applicable in various fields such as 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].
