Abstract
A inverse algorithm of rainbow detection was presented that permits one to get simultaneously the refractive index and size of droplet under low Signal-to-Noise Ratio (SNR) condition. The noise was removed based on Empirical Mode Decomposition (EMD) and feature points extraction technique. The parameters inversed according to a new built mathematic model and Debye theory. A numerical test and an experiment were taken to validate the algorithm. It is showed that the method greatly improves the accuracy of parameter inversion.
