Abstract (en)
[origin: WO9116638A1] A system for photoinductive imaging for flaw detection of materials and for calibrating eddy-current probes includes positioning an eddy-current probe (14) adjacent to a specimen (12) to be analyzed or to be used as a calibration fixture. A source of thermal energy (20) is modulated and focused to a localized area on the specimen. Thermal energy is then scanned across at least a portion of the detection area of the eddy-probe (14). The resulting signal from the eddy-current probe (14) is recorded and can depict either thermal-influenced components of the specimen (12) or the response pattern of the eddy-current probe (14). The record can therefore be used to image flaws or physical holes or shapes of the specimen or calibrate the eddy-current probe (14).
