SUMMARY:Innovation in Spatial Heterodyne Spectroscopy for Space Exploration
LOCATION:3853 Slichter Hall
DESCRIPTION:Date: 10/3/2025 (Friday)

Presented By: Dr. Seyedeh Hosseini – JPL
Abstract:High-resolution spectroscopy is essential for resolving fine spectral features that reveal important physical processes in planetary\, astrophysical\, and heliophysical environments. However\, traditional high-resolution instruments are large\, complex\, and incompatible with compact distributed space platforms. This talk presents the development of Spatial Heterodyne Spectroscopy (SHS) systems optimized for the FUV/EUV regime (10–200 nm) offering resolving powers of R = 20\,000–100\,000 in a compact form factor. We highlight critical advancements in instrument design\, including thermal\, optomechanical\, and detector integration\, as well as a validated system-level performance model. These innovations establish SHS as a scalable\, high-fidelity spectroscopic solution for the next generation of space science missions.
