Abstract

The Applied Sensing Laboratory at the University of Dayton has constructed a solar simulation laboratory to support polarimetric remote sensing research. The laboratory contains a number of highly accurate and repeatable motion stages that allow for automated positioning and control of imaging sensors, light sources, and object geometries. The laboratory contains both collimated (direct sun) and diffuse (downwelling) light sources that we have spectrally tuned to match expected solar irradiance under a range of outdoor conditions. In this work we describe the capabilities of the laboratory and the measures that have been taken to date for calibrating the laboratory environment to mimic outdoor solar conditions. The laboratory can support complex, automated experiments that can precisely control the dominant parameters of interest in polarimetric remote sensing. We demonstrate example data for laboratory use cases of interest to the polarimetric imaging community that include polarimetric bidirectional reflectance distribution function (pBRDF) measurements and generation of curated datasets to support polarimetric phenomenology studies and deep learning algorithm training for a host of polarimetric remote sensing applications.
