The Phasor Plot: A Universal Circle to Advance Fluorescence Lifetime Analysis and Interpretation

Annual Review of Biophysics, 2021
The phasor approach to fluorescence lifetime imaging has become a common method to analyze complicated fluorescence signals from biological samples. The appeal of the phasor representation of complex fluorescence decays in biological systems is that a ...

Fast Iterative-Interpolated DFT Phasor Estimator Considering Out-of-Band Interference

IEEE Transactions on Instrumentation and Measurement, 2022
For interpolated discrete Fourier transform (IpDFT)-based phasor estimators, the out-of-band interference (OOBI) test is among the most challenging ones.

Phasor measurement units, WAMS, and their applications in protection and control of power systems

Journal of Modern Power Systems and Clean Energy, 2018
The paper provides a short history of the phasor measurement unit (PMU) concept. The origin of PMU is traced to the work on developing computer based distance relay using symmetrical component theory.

Accurate Dynamic Phasor Estimation by Matrix Pencil and Taylor Weighted Least Squares Method

IEEE Transactions on Instrumentation and Measurement, 2021
Out-of-band interference (OOBI) test is a bench-mark test for M-class phasor measurement units (PMUs) in IEEE/IEC 60255–118-1-2018 and C37.118.1a-2014.

A Phasor Estimation Algorithm Robust to Decaying DC Component

IEEE Transactions on Power Delivery, 2021
Phasor measurement is widely used in fault detection and localization of power systems. To improve the phasor measurement accuracy when the fault signal contains the decaying dc component (DDC), this article proposes a half-cycle DFT (HCDFT)-based phasor

Non-line-of-sight imaging using phasor-field virtual wave optics

Nature, 2018
Non-line-of-sight imaging allows objects to be observed when partially or fully occluded from direct view, by analysing indirect diffuse reflections off a secondary relay surface.

Harmonic and Interharmonic Phasor Estimation Using Matrix Pencil Method for Phasor Measurement Units

IEEE Sensors Journal, 2020
This paper proposes a novel approach to estimate the fundamental frequency, harmonic and interharmonic phasors in power networks. The proposed method is based on the Matrix Pencil Method (MPM) and Principle Component Analysis (PCA).

Harmonic Phasor Estimation With Flat-Top FIR Filter

IEEE Transactions on Instrumentation and Measurement, 2020
The IEEE Std C37.118.1(a) describes synchrophasor measurement by a phasor measurement unit (PMU) for the system fundamental frequency. Harmonic synchrophasor, i.e., synchrophasor measured for harmonic frequencies, is not considered in the standard ...
