The radiation performance of the nanoporous thin film material prepared by the experiment was tested by using the visible-infrared spectrometer. Based on the experimental test data and using the pickup genetic algorithm, the radiation characteristics of the nanoporous thin film material were established based on the radiation transfer theory Problem research model. Using the inverse problem research model, the coefficients of reflectivity, optical constants and thickness parameters of Sellmeier equation of different species were calculated inversely, and the contrasted results were compared with the experimental results. The results show that the inverse problem The research model can accurately and quickly calculate the various radiation parameters of nanoporous thin film materials.
