Both measurements are performed using time domain reflectometry.
A Single Ended Line Probing (SELP) technique using combined Frequency Domain Reflectometry (FDR) and Time Domain Reflectometry (TDR) for characterizing a transmission medium.
The method for the differentiation of the surfaces is preferably laser reflectometry.
The invention relates to performing adjustable time domain reflectometry (TDR).
An improved Optical Coherence Domain Reflectometry (OCDR) system is provided.
The teachings of the subject invention lead to a new application of the XRR and RXRR systems.
The subject of the invention is also a reflectrometry system implementing the method.
A measured reflection profile of the optical channel, such as an OTDR trace, is provided.
The measurements made by the detector elements provide ellipsometry/ ref lectometry data for the test surface (124).
Polarization sensitive common path OCT/OCR devices are presented.
The mode of operation is especially useful as a way of providing high power pulses, for example for use in optical time domain reflectometry.
The sensors are suitable for a number of well-known electrical and electronic measurement processes (e.g. impedance measurement, reflectometers, resonance measurement).
The invention concerns a method and a device for detecting operating states by laser reflectometry with high laser power over an extensive spatial zone.
