This achievement marks a new height for China in the field of intelligent photon technology and high-precision imaging measurement. The related research results were published in the academic journal Nature as "Integrated Lithium Niobate Photonics Sub Emi level Snapshot Spectral Imaging".

The "Yuheng" chip is small in size, only about 2 cm x 2 cm x 0.5 cm, and does not require sacrificing flux in the wavelength dimension. Each pixel can obtain complete spectral information, and the resolution of snapshot spectral imaging (R=12000) has been improved by two orders of magnitude, breaking through the long-term bottleneck of not being able to achieve both spectral resolution and imaging flux.

Professor Fang Lu stated that the "Yuheng" chip has overcome the challenges of resolution, efficiency, and integration in spectral imaging systems, and can be widely applied in multiple fields such as machine intelligence, airborne remote sensing, and astronomical observation.

Taking astronomical observations as an example, "Yuheng" can obtain complete spectra of nearly 10000 stars per second, which is expected to shorten the spectral survey period of billions of stars in the Milky Way from thousands of years to less than ten years.

Moreover, with its miniaturized design, "Yuheng" can also be carried on satellites, and is expected to create an unprecedented cosmic spectral landscape for humanity within a few years.
