Abstract
A discharge detection system includes a plurality of optical fibers having different optical distances from each other and provided to allow discharge light generated from a test object to enter at least one of the optical fibers, an optical sensor configured to detect the discharge light having entered the at least one of the optical fibers and to output a detection signal having a temporal change in an amplitude of the detection signal, the temporal change in the amplitude corresponding to a temporal change in intensity of the discharge light, and a signal processing system configured to identify an area where the discharge light is generated based a point of time of at least one peak in the detection signal.
