About

Alexei Shapkin is a leading figure in the development of advanced infrared spectrometer systems for planetary exploration, with a particular focus on acousto-optic tunable filter (AOTF) technology. His most cited work, "Development of a mast or robotic arm-mounted infrared AOTF spectrometer for surface Moon and Mars probes" (2015, 19 citations), introduces a compact, pencil-beam spectrometer designed for in situ mineralogical analysis of planetary surfaces. This instrument operates in the near-infrared range, analyzing reflected solar radiation to assess surface composition. A key achievement of this research is its application to the ISEM (Infrared Spectrometer for ExoMars) instrument, a critical payload for the ExoMars rover mission. Shapkin’s contributions enable robotic probes and rovers to perform real-time, non-destructive mineralogical surveys, directly supporting the search for past or present life on Mars. His work bridges cutting-edge optical engineering and planetary science, providing a robust tool for context assessment of surface geology. With 19 citations, this paper underscores his impact on the design of compact, rugged spectrometers for space missions, influencing future instrument development for Moon and Mars exploration.
