Abstract:
1. A system for measurement with at least one pearl, comprising: at least one signal conductor; and a plurality of pearls, wherein each of said plurality of pearls comprises a device configured to change an impedance mismatch with an external environmental effect, the device comprising a reflector; and an isolator with a thermal coefficient of expansion, wherein the device is configured in a manner such that the external environment effect changes a size of the isolator, which in turn changes at least one of a size of the reflector and a distance between the reflector and the at least one signal conductor, giving rise to a change in impedance mismatch which in turn changes degree of reflection, and wherein said plurality of pearls are separately arranged along the at least one signal conductor, and each of the plurality of pearls is independent of each other.
