Abstract
PURPOSE: To enhance the S/N and thus to ensure the high-accuracy detection for the defect by giving the prescribed delay process via the clock which is based on the shift velocity of the detected object and thus securing the simultaneous generation of the detection output for plural detectors arranged in the carrier direction.
CONSTITUTION: With application of the shift velocity signal of the detected object through velocity detector 9, clock pulse generator 8 generates the clock featuring the cycle suited to the shift velocity and then applies the clock signals to analog signal delay circuits 51, 52... corresponding to eddy current type defect detectors 41, 42... which are installed in sequence in the shift direction. As a result, the detection output given from detectors 41, 42... are delayed in accordance with the installation positions of these detectors, and thus an addition is given by supposing that detectors 41, 42... have the simultaneous generation of the detection output through adder 6 to increase the defect detection output. As a result, the S/N can be enhanced to ensure the high-accuracy detection of the defect for the mobile object.
