The vacuum cabin experimental device includes a vacuum cabin, A humidity control unit connected to the vacuum chamber, an air supply unit connected to the humidity control unit, and a temperature control unit placed outside the vacuum chamber. The vacuum chamber is equipped with a cold and hot platform and a sample holder. The temperature control unit is connected to the cold and hot connection; the full-spectrum characterization and joint experiment device includes at least two spectrometers outside the vacuum chamber, each spectrometer is connected to a sensing element, each sensing element is connected to a light source, the sensing element is located in the vacuum chamber, and the light source Located outside the vacuum chamber. The invention can simulate the Martian environment, and collect samples from ultraviolet, visible near-infrared to mid-infrared and Raman spectra in the simulated Martian environment, fully grasp the coupling relationship between Martian environmental conditions and sample spectra, and use it for Mars remote sensing and positioning Comparison and interpretation of probe spectral data.

Description

technical field [0001] The present invention relates to the technical field of spectrum experiment, and relates to the spectrum experiment technology under the Mars simulation environment, in particular, to a full-spectrum in-situ characterization and joint experiment device and method under the Mars simulation environment, which is used for different Mars simulation environment conditions A variety of spectroscopic comprehensive in situ tests. Background technique [0002] Like the earth, Mars has a variety of landforms, including mountains, plains and canyons, and the surface is covered with sand dunes and gravel. Mars also has an atmosphere, but its main component is CO 2 (~95.5%), and the air pressure is very low (~600-1000Pa), and the global annual average temperature is as low as -63°C. The spectroscopic characteristics (such as ultraviolet spectrum, visible-near-infrared reflection spectrum, mid-infrared spectrum, Raman spectrum, etc.) of the material composition on ...

AI Technical Summary

Problems solved by technology

At present, there are no domestic reports on in-situ spectral characterization experiments in a Mars simulation environment. Although some spectral characterization experiments have been reported abroad, most of them were not conducted under simulated Mars environmental conditions. Mineral / salt experiments are mainly characterized by a single spectrum, and the spectral information obtained is relatively single, and there is a lack of related experiments that combine multiple spectral techniques for comprehensive in-situ characterization
