TEM measuring apparatus and method of identification of anomalies orientation recognition

The present invention relates to a transient electromagnetic measuring apparatus and method for identifying anomalies orientation recognition device comprises transmitting coil, receiving coil and double fixing means; said double receiving coil by the first receiving coil and a second receiving coils, the two holding fixed pitch and parallel to the two symmetrical fastening means each corresponding to the surface, and connected via a respective channel receiver. The same as the first winding and the second receiving coil receiving coil direction. The fixing means is a polygonal columnar body has at least two mutually parallel surfaces thereon. In one aspect of the present invention, the double parallel receive coil design in which a receiving coil for detecting direction is measured using the other receiving coil in the opposite direction to distinguish the sensing signal, the whole space may be distinguished effect of the anomaly is determined to achieve full spatial orientation conditions ; another aspect, the present invention can improve the efficiency of the device construction site, greatly reducing post-data processing workload.
