About

Igor Stupin is a space instrumentation physicist whose work centers on the development of Fourier-transform spectrometers (FTS) for planetary exploration, with a particular focus on Mars. His key research areas include interferometer design, optical alignment, and robotic mechanisms for space-based spectrometers. Stupin’s major contribution is the design and validation of a novel Michelson interferometer employing hollow retroreflectors and a single-axis robot, a configuration that dramatically simplifies alignment and increases mechanical stability under harsh extraterrestrial conditions. This work, detailed in his most-cited paper, “Interferometer with single-axis robot: design, alignment and performance” (2019, 3 citations), directly supports an FTS instrument intended to operate on the Martian surface, capable of observing the solar disc in two distinct regimes. While his citation count is modest, the impact of his engineering is significant: his design addresses a critical bottleneck in compact, rugged spectrometer development for planetary missions. Stupin’s contributions are foundational for next-generation atmospheric and surface composition studies on Mars, positioning him as a key technical innovator in the field of space-based optical instrumentation.
