| Outline of Final Research Achievements |
For fast non-destructive inspection system using the weak magnetic signal images detected by the magnetic excitation field controlled in both the time-domain and the space-domain, The excitation coil pair design, its characteristic evaluation, and the location design of the coil pairs were done. The contaminant position estimation procedure was considered. In addition, the active noise control system using the adaptive filter with single input signal was considered. In this system, the reference signal was reproduced by the correlation between the actual noise and input signal. Also consider for a wide band SQUID FLL circuit was performed and the correction system for the sensitivity variation was investigated. Furthermore investigation of the basic operation of the detection system were made.
It was considered the suitable excitation signal was not a pseudo-DC signal, but AC signals with different frequencies which were applied to each of coils.
