Rainbow Thermometry Based on EMD De-Noising and Signal Analysis
Qi Pan · Procedia Engineering · 2012
A novel Rainbow thermometry method is presented which is based on Empirical Mode Decomposition (EMD) denoising and signal analysis, and permits one to get simultaneously the temperature and size of droplet under low Signal-to-Noise Ratio (SNR) condition. The noise is removed based on EMD and wavelet threshold method, and the inverse parameters are calculated according to the signal decomposition analysis based on EMD. A experiment is taken, and the measurement result shows the validity of the presented method.
