Polarization Changes in Lunar Simulant Soil: The Role of Incident, Reflection, and Off‐Plane Angles

Earth and Space Science, Volume 13, Issue 4, April 2026.
Abstract Observing the polarization of the lunar regolith is essential for obtaining detailed information about the composition and characteristics of lunar soil. Observations conducted via lunar orbiters facilitate polarization measurements over wide areas; however, achieving very high‐resolution imaging requires either a large optical system or a ...
