超音波を利用した「表面弾性波の計測技術」no.１４
"Measurement technology of a surface elastic wave" using an ultrasonic wave
複雑に変化する表面弾性波の受信データを、時間や電圧レベルで、単純に評価しません。
Neither time nor a voltage level estimates simply the received data of the surface acoustic wave which changes intricately.
「弾性体に対する伝播状態全体」を考慮するために、時系列データの自己回帰モデルを作成し、
バイスペクトル解析・・・で、評価・応用しています
In order to take into consideration the "whole" propagated state over an elastic body, the autoregressive model of time series data was created, and it has evaluated and applied by bispectrum-analysis ---.
超音波の発振制御技術と
受信データの分析技術の組み合わせにより
今後、幅広い応用が実現すると考えています
I think that broad application will be realized from now on with the combination of the oscillation control technology of an ultrasonic wave, and the analytical skills of receiving data.
