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 nano

Embodiment Construction

[0035] A high-performance imaging spectrometer with high spatial and high spectral resolution of the present invention consists of one or more sets of spectral sensors, a motion platform and stage, auxiliary optical devices, controllers and control software, calibration devices, etc. Composition, each component module can be combined freely. Under the management of the control software, the device can use the spectral sensor to obtain the spectral information or radiance information of a point in space under the set imaging process (mode), and then use the motion platform to drive the movement of the spectrometer sensor to image the object in space. The information of other points can be used to obtain hyperspectral images with high spatial resolution and high signal-to-noise ratio under controllable conditions. The device can simulate different imaging processes and imaging methods through different motion modes of the multi-degree-of-freedom motion platform, and can simulate...

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...
