Abstract

The FORMOSAT-8 Program aims to develop high-resolution optical remote sensing satellites through collaboration with industry, academia, and research teams in Taiwan. In order to enhance the signal-to-noise ratio (SNR) of the images, it is crucial to understand the surface scattering characteristics and implement effective measures to suppress stray light in the optical system. In this study, a combination of bidirectional reflectance distribution function (BRDF) and total integrated scattering (TIS) measurements is utilized to identify materials that exhibit ultra diffusive-matt characteristics. All the selected materials underwent environmental tests to verify their durability for space environment usage. The databases of BRDF and TIS also facilitate the construction of mathematical models representing surface scattering characteristics. All the findings of this study were utilized to arrange the surface blackening methods for various components within the optical system and proved highly advantageous for FORMOSAT-8 satellite program.
