Equipped with a point spectrometer and two hyperspectral cameras spanning the visible near-infrared range (0.4–2.5 µm), the hyperspectral remote sensing laboratory is dedicated to reflectance spectroscopy studies.
Acquired rock and powder spectra are processed with state-of-the-art, dedicated software (ENVI, BREEZE/EVINCE, Mineral Recognizer).
Although these instruments have numerous possible applications, at the CRPG they are mainly used for planetary analogue studies (ground-truthing of remote sensing data in the field, building new reference spectral libraries for Mars and the Moon….).
Two calculation servers and 150 TB of dedicated storage are available for associated data processing and storage.

Laboratory scanning stage
The large rack allows multiple cameras to be used at the same time in the laboratory, at a maximum 1-metre working distance, and supports lamps for sample illumination.
Field setup
Coupled with a rotation stage, our field tripod allows the outdoor scanning of up to two cameras positioned horizontally.
DATA ACCESS
The data produced in the CRPG hyperspectral remote sensing laboratory are published as the open-access spectral library Mirabelle, which is accessible via the free interface S-SHADE: https://www.sshade.eu/db/mirabelle
