— 1 min read

Researchers from the iGaN Laboratory, led by Professor Haiding Sun, have successfully developed the world's first miniaturized ultraviolet (UV) spectrometer, utilizing a novel gallium nitride (GaN) cascaded photodiode architecture and integrated with deep neural network (DNN) algorithms. This innovative device achieves high-precision spectral detection and high-resolution multispectral imaging, with a response speed on the nanosecond scale. The technology has vast applications in material analysis, environmental monitoring, satellite remote sensing, and deep-space exploration.

Key Takeaways:

  • The iGaN Laboratory, in collaboration with Wuhan University, Zhejiang University, and University of Cambridge, developed a miniaturized UV spectrometer with high-precision spectral detection and high-resolution multispectral imaging capabilities.
  • The device utilizes a novel GaN cascaded photodiode architecture and integrated DNN algorithms, achieving a response speed on the nanosecond scale.
