Abstract
Description
여기서, 상기 각 진동자(14)는 도 6에서와 같이 융기부(3)로 부터 제각각 입사되는 에코 초음파가 모두 입사되게 하기 위해 도 5에서와 같이 각 진동자(14)의 설치 높낮이를 에코 초음파의 입사각에 맞춰서 서로 다르게 배치하는 것이 바람직하다.
Claims (6)
- 하우징의 내부에 복수의 격실을 두고, 상기 격실에는 전원단자와 케이블로 연결된 진동자가 내장되어 있으며, 일측면에는 상기 각 진동자로 부터 초음파가 발진되고 또, 피검체의 다중 목표물에 반사되어 되돌아오는 에코 초음파가 입사되는 투명한 아크릴 판이 설치된 탐상 본체;상기 탐상 본체의 타측면에 위치하며, 원호형 장공이 형성되어 있어서 이 장공을 관통하는 조임볼트에 의해 상기 탐상 본체와 체결되고, 지그에 의해 피검체에 고정되는 고정편;으로 구성된 것을 특징으로 하는 다채널형 초음파 탐상장치.
