고분자(高分子) PVDF 진동자(振動子)를 이용(利用)한 점집동초음파탐촉자(点集東超音波探觸子)의 특성
Characteristics of Point-Focus Type Ultrasonic Transducer using PVDF Element
초록
In this study, we examine the characteristics of beam and the effect of these characteristics on the flaw detection by using different type of two transducers, which are PZT and PVDF film transducer. Consequently, the detection of infinitesimal flaw is more possible than PZT, since it has beam width at focus of
