US 9,869,607 B2 · Systems and methods for distributed measurement

Abstract

A measurement system includes a cable having a length, a light source, at least one detector, and at least one processor. The light source is operably coupled to the cable and is configured to transmit an optical signal to the cable. The at least one processor is operably coupled to the cable and configured to: receive a scattered signal from the cable responsive to the optical signal transmitted to the cable; map the scattered signal to the length of the cable; and de-convolve a spatial averaging effect of the scattered signal using a weighting profile corresponding to the light source and the cable to generate a distributed property profile defined along the length of the cable.

Dependent claims

A time domain distributed measurement system comprising:

a cable having a length;
a light source operably coupled to the cable and configured to transmit an optical signal to the cable;
at least one detector operably coupled to the cable;
and
at least one processor operably coupled to the at least one detector and configured to:
receive a scattered signal via the at least one detector from the cable responsive to the optical signal transmitted to the cable;
map the scattered signal to the length of the cable;
and
de-convolve a spatial averaging effect of the scattered signal using a weighting profile, wherein the weighting profile is determined based on a combination of the light source and the cable to generate a distributed property profile defined along the length of the cable.
