Description
Underground environments present a challenge for hyperspectral outcrop analysis. Besides operational safety and moisture, illumination is the main challenge in data acquisition. Building on preliminary results of an earlier campaign in which we used artificial light in combination with a HySpex camera to illuminate rock faces in a former gold mine in southeast Spain (van der Werff et al. 2024), we now report on advances with improved alignment, calibration, and mobility as deployed in an underground mine, Reiche Zeche, Freiberg, Germany.The results presented will provide valuable insight and commentary on the viability of utilising artificial illumination in hyperspectral data acquisition in areas previously unable to do so. We will show comparative results of daylight vs. alternative artificial illumination. Furthermore, we comment on the preliminary foundational assumptions for processing and interpretation of data capture in a proximal artificially illuminated environment to work towards identifying key minerals that may be used as a vector toward ore zones.
