Project Description

To prepare for scientific investigations at Psyche, meteorite experts from ASU and the Smithsonian Institution are seeking an imaging system to help determine the bulk chemical compositions of iron meteorites from their optical images . Meteorite experts use their knowledge to recognize the inclusions in meteorites based primarily on color, texture, and reflectivity. A major challenge of this project is to translate this human knowledge to an automated recognition system the can replicate the human expertise. To work towards this goal, the team designed and built a prototype imaging system to image meteorite samples so that each image has the exact same lighting and image quality.
