A Compact MEMS-Based Fabry–Pérot Infrared Spectrometer for Planetary Surface Exploration

Kurzfassung

Thermal infrared spectroscopy provides essential information on the mineralogical and physical properties of planetary surfaces through diagnostic emissivity features such as the Christiansen feature, Reststrahlen bands, and transparency features. However, the implementation of thermal infrared spectrometers on small satellites, landers, and rovers remains challenging due to strict constraints on mass, power, and system complexity. This contribution presents the development and laboratory validation of a compact Fabry–Pérot infrared point spectrometer optimized for resource-constrained Solar System exploration missions.
