Broadband Spectral-Polarimetric BRDF Scan System and Data for Spacecraft Materials

Abstract

A broadband spectral-polarimetric Bidirectional Reflectance Distribution Function (BRDF) measurement system from 350nm to 2500nm with 1nm wavelength resolution is providing data for satellite radiance modeling and specifically for Michigan Tech's OCULUS-ASR space mission. The satellite has four deployable panels, which are covered with solar cells on one side, and are brightly colored on the other. BRDF data for the colored panels show interesting spectral features, including wavelength variability of first surface scatter, volumetric scatter and second surface scatter. Additional surface scatter data for other spacecraft materials including anodized aluminum, multilayer insulation (MLI) and solar cells is presented. The continuum nature of the data indicates that either dedicated BRDF models or a method for incorporating complex wavelength data into simulations will be needed for passive spectral radiance modeling and accurate spectral correlations.
