Subpicosecond-time-domain reflectometry

Optics Letters, 1981
We demonstrate a new method of optical time-domain reflectometry using subpicosecond pulses and nonlinear detection. The high-spatial-resolution ( approximately 15-microm) temporal resolution and sensitivity put new limits on the size and nature of defects that can be detected, localized, and analyzed in optical fibers.

Simulation of Time-Domain Reflectometry

open access: yesApplied Mechanics and Materials, 2017
This paper introduces a simulation work of Time-Domain Reflectometry (TDR). The TDR analysis begins with the propagation of a step or impulse of energy into a system and the subsequent observation of the energy reflected by the system. By analyzing the magnitude, duration and shape of the reflected waveform, the nature of the impedance variation in the

Time-domain reflectometry in carbohydrate solutions

Journal of Food Engineering, 1995
With time-domain reflectometry (TDR) the dielectric permittivity of foodstuffs can be measured with the use of a cheap cable tester, which has proved its value in soil science. The materials which are examined are solutions of mono-, di- and polysaccharides.

Diagnosis of Multiple Wiring Faults Using Time-Domain Reflectometry and Teaching–Learning-Based Optimization

open access: yesElectromagnetics, 2015
Time-domain reflectometry has proven to be one of the best methods for wiring network diagnosis, and it can easily be applied to the detection and localization of defects, while only requiring one access point to the wiring network.

Time extraction method for time domain reflectometry measurements

2015 IEEE Sensors Applications Symposium (SAS), 2015
Determination and monitoring of moisture content in the soil is a requirement in many agricultural and civil engineering applications. Time domain reflectometry (TDR) is a well-known technique for its accuracy and applicability in the field. A typical TDR system consists of three units: A signal generation unit, a signal acquisition and encoding ...
