Four-dimensional spectral imaging technology is a revolutionary new imaging technology. The 4D imaging spectrometer breaks through the traditional spectrometer imaging method and acquires image and spectral data with high-speed imaging. A set of systems can simultaneously acquire spatial, spectral, and time-resolved (transient) hyperspectral information with special ability to capture fast events. With the video recording function, the imaging spectrometer can be smaller in size and more flexible in design.
The project team closely followed the international frontier development trend, expanded ideas, and actively carried out theoretical research on four-dimensional spectral imaging technology. Based on a large number of previous research, it designed and developed a 4D imaging spectrometer desktop experimental device, and carried out imaging experiments, verifying the four-dimensional The feasibility of the theory of spectral imaging technology enables a snap-shot acquisition of data cubes, enabling rapid processing of real-time display and analysis.
This technology has important theoretical significance for improving the level of domestic digital remote sensing technology and satisfying the urgent need for domestic acquisition of hyperspectral remote sensing images.
Recently, the 508 four-dimensional spectral imaging technology team of China Academy of Aeronautics and Astronautics Co., Ltd. carried out four-dimensional imaging spectrometer imaging experiments, successfully verified the ability of the technology in the acquisition of four-dimensional spectral imaging, and added another field for snapshot hyperspectral imaging. The new members have made up for the gap in the field of domestic high-speed target dynamic capture products.
