  • Magnetism detecting system
    Patent number: 3971981
    Abstract: A magnetism detecting system, in which reference magnetic fields sequentially scan many radial scanning lines obtained by dividing a plane to be detected at regular intervals of a desired angle with respect to an origin positioned at the common intersecting point of said scanning lines. At least one parametrically excited second harmonic oscillator detects the direction and magnitude of a magnetic field to be detected along each of the scanning lines. A display device is provided for scanning and displaying the plane with respect to the origin in synchronism with the scanning of each of the scanning lines. A detected output is applied to the display device when the magnetic field to be detected and the reference magnetic field coincides with each other in direction and in magnitude.
