Time-domain reflectometry (TDR) is one of the most common methods used for fault classification and location.
The final output of a reflectometry measurement is the reflectivity R (defined as reflected intensity divided by incident intensity of the probe radiation) as a function of the scattering vector [??] (defined in terms of the change in the momentum [??] of the scattering radiation as [mathematical expression not reproducible]).
The SS-OCT biometer also measured the AL with fewer measurement failures than achieved with an optical low-coherence reflectometry (OLCR), the Lenstar 900; 96% measurements were successful with the SS-OCT, whereas 72% were successful with the OLCR [7].

Although time domain reflectometry (TDR) is increasingly being replaced for irrigation management by methodologies that are cheaper and easier to use, it remains important for accurate monitoring of soil water in time and space for research purposes, especially in hydrological modelling.
The advantages (e.g., smaller via dimension and via stub removal) and challenges (e.g., crosstalk due to smaller inter-pair separation) of HDI are studied by analyzing the S-parameter, time-domain reflectometry (TDR) and transmissionline eye diagrams obtained by three-dimensional electromagnetic modeling (3DEM) and 2-D electromagnetic modeling (2DEM) using Mentor Graphics' HyperLynx and Keysight Advanced Design System (ADS) CAD software.
Electronic device circuit quality analysis is commonly performed using oscilloscope TDR (time domain reflectometry).
