Filter based phase distortions in extracellular spikes. [PDF]
PLoS ONE, 2017 Extracellular recordings are the primary tool for extracting neuronal spike trains in-vivo. One of the crucial pre-processing stages of this signal is the high-pass filtration used to isolate neuronal spiking activity.

Phase Distortion by Linear Signal Transforms [PDF]
Frontiers in Applied Mathematics and Statistics, 2020 In this study, we are concerned with the effect of certain linear transformations of a signal f on its phase. We are, in particular, interested in phase distortions caused by band-limiting operations. The band-limiting operators serve as a motivation for

Compensation for phase distortions in nonlinear media by phase conjugation [PDF]
Optics Letters, 1980 We demonstrate theoretically that the distortion-correction property of phase-conjugate beams propagating in reverse through aberrating media is also operative when the indices of refraction of the media depend on the intensity.

Phase distortions of attosecond pulses produced by resonance-enhanced high harmonic generation [PDF]
New Journal of Physics, 2013 Resonant enhancement of high harmonic generation can be obtained in plasmas containing ions with strong radiative transitions resonant with harmonic orders. The mechanism for this enhancement is still debated.

Estimation of phase distortions of the photoplethysmographic signal in digital IIR filtering [PDF]
Scientific ReportsPre-processing of the photoplethysmography (PPG) signal plays an important role in the analysis of the pulse wave signal. The task of pre-processing is to remove noise from the PPG signal, as well as to transmit the signal without any distortions for ...

Reconstructing the Spatial Parameters of a Laser Beam Using the Transport-of-Intensity Equation
Sensors, 2022 A simple method for reconstructing the spatial parameters of a laser beam, based on the transport-of-intensity equation, is presented. Registration of cross-section intensity distributions in several planes was carried out using a single CMOS camera. The

Computational Method for Wavefront Sensing Based on Transport-of-Intensity Equation
Photonics, 2021 Recently the transport-of-intensity equation as a phase imaging method turned out as an effective microscopy method that does not require the use of high-resolution optical systems and a priori information about the object.
