本文论述了新一代的超声发射与接收系统。它通过光导纤维将激光脉冲发射到试样上,探测器采用带中心孔的电磁声换能器,以使光导纤维通过。同时,本文还提供了铝和钢试样的超声波形图。
This article discusses a new generation of ultrasound transmit and receive systems. It emits laser pulses through an optical fiber onto a sample, which uses an electromagnetic transducer with a central hole to pass the optical fiber. At the same time, this article also provides ultrasonic charts of aluminum and steel samples.
