Summary:Highly emissive spaceborne blackbody radiation sources are important devices for infrared value traceability by providing accurate infrared radiation to calibrate infrared load. To meet the needs of the radiation calibration accuracy needed for infrared remote sensing, this paper proposes a highly emissive blackbody that uses cubic reflection and an absorption method based on light capture. An emissivity simulation based on ray tracing was carried out. The influences of specular reflection (SR), near specular reflection (NSR), and diffuse reflection (DR) on the emissivity of the blackbody were analyzed. Two blackbodies with NSR and DR were fabricated, simulated, and tested experimentally; the experimental and simulation results were consistent.
