Paper Abstract

In order to meet the experimental requirement of in-situ measurement for spectral reflectance of advanced thermal control coatings, a high accuracy in-situ measurement system for spectral reflectance of thermal control coatings of spacecraft is developed based on dual-beam spectrophotometry. The measurement wavelength range is 200 to 2500 nm, and the measurement accuracy is better than 0.5%. In the space ultraviolet radiation environmental effect test, it can realize the integrated test process of sample delivery, sampling, separation, in-situ measurement of spectral reflectance in vacuum.
