Reflectometry

Reflectometry is a noninvasive technique that allows the analysis of properties of a medium. This technique is based on the reflection of waves at the interface of interest. Waves propagate into a medium (according to the laws of propagation into the medium studied) and when they encounter a discontinuity (impedance break), part of their energy is reflected back to injection point. The analysis of the reflected signal can infer information about the system or the medium under consideration.

Application fields

The fields of application are very diverse and involve many sectors:

Different reflectometry techniques

Many techniques are based on the principle of reflectometry and are distinguished by the type of waves used and the analysis of the reflected signal. Among all these techniques, we can classify the main but not limited to:
