Description

technical field [0001] The invention relates to the technical field of remote sensing imaging, and is a high-performance imaging spectrometer with high spatial and high spectral resolution. Background technique [0002] With the development of national economy and remote sensing technology, hyperspectral measurement and imaging technology has gradually been applied and developed in vegetation, geology, environment, military and other fields. At present, ground spectrometers and aerospace hyperspectral imaging have been widely used. [0003] Ground-based spectrometers can obtain spectra, but do not have imaging capabilities, making it difficult to grasp the nature of targets. However, it has the advantages of simple operation, high signal-to-noise ratio, and easy calibration. [0004] Space-borne and airborne hyperspectral imagers rely on the flight of the carrier to achieve imaging of facing targets, but at the same time have disadvantages such as low spatial resolution (g...

AI Technical Summary

Problems solved by technology

[0004] Space-borne and airborne hyperspectral imagers rely on the flight of the carrier to achieve imaging of facing targets, but at the same time have disadvantages such as low spatial resolution (generally at the meter level or even 10 meter level) and low spectral resolution (greater than 10 nanometers). Greatly limit the detailed study of ground features

At the same time, aviation and aerospace hyperspectral imaging are easily affected by the atmosphere and the environment, and it is not convenient for synchronous calibration, which also has a certain impact on the study of ground objects.
