摘要： The apparatus of the present invention comprises: an excitation device which excites the measurement site with a local direct-current or alternating-current magnetic field, and a plurality of magnetic field detection devices which are disposed in proximity to each other to measure the magnetic field component that is perpendicular to the exciting magnetic field. A magnetic fluid that possesses paramagnetism is injected from the outside into a substance in which a fluid can flow, and the local magnetic field gradient is then measured while the injected magnetic fluid is excited by the application of a direct-current or alternating-current magnetic field from the outside, thus measuring the presence or absence of distortion of the local magnetic field distribution arising from the fact that the specific magnetic permeability of the magnetic fluid injected into the substance is higher than that of the surrounding substance, so that sites where large amount of the magnetic fluid has accumulated are identified in a non-invasive manner without being affected by external magnetic noise.

摘要： In a SQUID magnetometer, high resolution, a high slew rate, and a high dynamic range are achieved without using expensive circuit components having a large number of processing bits and enabling a high speed processing operation. A digital FLL circuit using a double counter system is provided. This circuit utilizes two or more counters, for example, a change range counter in a digital FLL for carrying out a processing operation at a high speed and a reproducing counter in a control/measuring computer. In addition, in the present invention, hysteresis characteristics having a 1Φ0 positive margin is used. That is, a change of a state of a magnetic flux is counted by means of a counter. At the time of this change, control is made so as to track a different channel between cases in which a magnetic flux increases and decreases, thereby stabilizing the control.

摘要： A current to be applied to a ground is defined as the sum of two sinusoidal waves having first and second frequency components. A signal to be used at the time of synchronous detection is defined as a difference between the sinusoidal waves having the first and second frequency components. As a result, a substance in the ground, and the position and depth of the substance can be specified with high accuracy.
