  • To develop a diffuser for CO2 detector calibration, the process of physical grinding and chemical etching was used to produce the test specimens of the aluminum diffuser for the CO2 detector calibration, and their test devices for relative Bidirectional Reflectance Distribution Function(BRDF) and hemispherical reflectance were built. In the case of 0 and 45 of the incident lights, the test results for visible to near-infrared band, show that the surface roughness affects Lambert characteristics of the aluminum diffuser and the Lambert characteristics of the diffuser made of 240# abrasive grit is the best. Chemical corrosion can not only improve Lambert characteristics of the aluminum diffuser, but also can improve the hemispherical reflectance. When etching temperature is selected at 20℃ and the concentration of NaOH solution is in 52.6 g/L, the optimal time of corrosion is about 4 min. Aluminizing makes hemispherical reflectance of aluminum diffuser to be improved by 20% on average, but it makes Lambert characteristics deteriorated. Furthermore, the relative BRDF of aluminum diffuser is slightly different at different wavelengths, but shows the same trend. The experiments in this paper determine the key parameters affecting the diffuse reflection characteristics of the diffuser, quantitatively optimize process parameters, and provide a basis for the further development of the diffuser for CO2 detector calibration on orbit.
