Abstract
According to the invention, these aims are achieved by means of a sensor, suitable for sensing one or more properties of one or more structures, the sensor comprising, a first optical propagation path which is configurable to cooperate with a structure whose properties are to be sensed; a second optical propagation path which is configurable to cooperate with a structure whose properties are to be sensed; a third optical propagation path; a means for amplifying a signal which propagates in the third optical propagation path, so that the signal is amplified before it begins propagation along the second optical propagation path, and a means to prevent the propagation of signals from the second optical propagation path to the third optical propagation path. There is further provided a corresponding method of sensing.
