A Goniometric System for Photometric and Polarization Measurements of Planetary Regolith Analogs

Earth and Space Science, Volume 12, Issue 9, September 2025.
Abstract The Planetary Surface Texture Laboratory at the Johns Hopkins University Applied Physics Laboratory is a facility for the study of the photometric and polarization behavior of regolith analogs using an ∼1.5‐m‐radius arc goniometer system. This system characterizes the photometric and polarization response of granular materials (planetary ...
