Robust algorithms for quantifying noisy signals of optical fiber probes employed in industrial-scale practical bubbly flows

► Categorization of the noise into several types based on the noise analysis. ► Development of two types of new algorithms: Histogram and Median methods. ► Verification of the performance of them compared with the conventional min-max method. ► Demonstration of their performance in analyzing the noisy signals from experiments. ► Definite robustness of the new algorithms.
