Lei Peng et al., published journal article in IEEE Transaction on Instrument and Measurement with the title “Fastener Tilt Assessment Based on Magnetic Field Image Obtained with Array Tunnel Magnetoresistance Sensors” in 2020

Release time:2020-09-20

Lei Peng, Na Zhang, Yu Tao and Chaofeng Ye published journal article in IEEE Transaction on Instrument and Measurement with the title “Fastener Tilt Assessment Based on Magnetic Field Image Obtained with Array Tunnel Magnetoresistance Sensors” in 2020. This paper proposed a new probe with array tunneling magneto-resistance (TMR) sensors for tilt assessment. An image-processing algorithm has been developed for assessing the tilt from the magnetic image generated by the probe. Experiment results show that the probe can discriminate fasteners that tilt in any orientations from well-mounted ones. The probability of detection and probability of false alarm are 90.9% and 13.1% respectively for a fastener with tilt altitude difference 0.27 mm along the scan direction.
