Title:
超音波検査の信号処理方法及び装置並びに厚み計測方法及び装置
Document Type and Number:
Japanese Patent JP7369059
Kind Code:
B2
Abstract:
A signal processing method for ultrasonic inspection includes: a step of generating ultrasonic waves by driving an ultrasonic probe by using a plurality of burst wave signals with different frequencies, respectively, and causing the ultrasonic waves to inject an inspection target; a receiving step of receiving a plurality of multiple reflected waves corresponding to the plurality of burst wave signals having injected the inspection target, respectively; a step of obtaining a plurality of detection signals by executing detection processing of receiving signals of the plurality of multiple reflected waves corresponding to the plurality of burst wave signals, respectively; and a generating step of generating an inspection signal for obtaining an inspection result related to the inspection target by using the plurality of detection signals.
