Determination of Satellite Observables. Volume 4. Optical Properties of Satellite Materials
Abstract
The optical properties of selected satellite surface materials were measured; these materials included solar cells, thermal control mirrors, reflective tape, and various painted surface. All samples were prepared using actual vehicle substrates and flight test assembly procedures. Measurement data reported include: (1) spectral directional reflectance and/or emittance over the UV0.24- to IR22- micrometers spectral range; (2) bidirectional reflectance at coherent wavelengths of 0.63, 1.06 and 10.6 micrometers and a visible solar simulation band extending from 0.4 to 0.7 micrometers; and (3) surface distribution information on samples having a significant specular component -- given as direction normal orientation of individual sample elements. Instrumentation measurement techniques are discussed, and the results, showing significant specular returns from solar cells, are presented in tabular or graphical format. Data interpretation and variability are also discussed.
