Noise due to scattered light has been a frequent disturbance in the Advanced LIGO gravitational wave detectors, hindering detection of waves. The non stationary scatter noise caused by low frequency motion can be recognized as arches time-frequency plane channel. In this paper, we characterize scattering for LIGO's third observing run O3 from April, 2019 March, 2020. We find at least two differ...

Scattered light noise affects the sensitivity of gravitational waves detectors. The characterization such is needed to mitigate it. time-varying filter empirical mode decomposition algorithm suitable for identifying signals with time-dependent frequency as scattered (or scattering). We present a fully automated pipeline based on pytvfemd library, python implementation tvf-EMD algorithm, identif...

In quiescent rat ventricular myocardium, bathed in solution of 2 mM Ca++ or less, it has been previously demonstrated that spontaneous microscopic oscillatory cell motion is present and interacts with an incident laser beam to produce scattered light intensity fluctuations which can be monitored to quantify the underlying motion. The present study shows that scattered light intensity fluctuatio...
