Claim 0:
1. An optical sensing system comprising:
an optical fiber comprising one or more optical sensors;
a light source placed at a first end of the optical fiber, wherein the light source is configured to direct light towards the one or more optical sensors;
a first interrogator placed at the first end of the optical fiber;
a second interrogator placed at a second end of the optical fiber, opposite to the first end, and
a comparing unit;
wherein the first interrogator is configured to receive light reflected from the one or more optical sensors, and the second interrogator is configured to receive light transmitted from the one or more optical sensors,
wherein the first interrogator is configured to analyze the light reflected from the one or more optical sensors to determine changes in strain or temperature along the optical fiber,
wherein the second interrogator is configured to analyze the light transmitted from the one or more optical sensors to determine changes in strain or temperature along the optical fiber, and
wherein the comparing unit is configured to compare the change in strain or temperature determined by the first interrogator with the change in strain or temperature determined by the second interrogator.
