On-Demand Webinar:

Quality, Test & Measurement

Date: September 15, 2010
Time: 2 PM EDT (11 AM PDT)
Duration: 1 hour


Acoustic microscopy, also known as acoustic micro imaging or AMI, is a nondestructive inspection technology that employs high-frequency ultrasound to find hidden defects such as delaminations, voids, and cracks. Because ultrasound cannot propagate through air at AMI frequencies, the inspection technique provides valuable feedback about component quality. This presentation introduces the basic principles of acoustic microscopy; explains how an acoustic image is generated using focused ultrasonic transducers; and offers application examples from the semiconductor, aerospace and defense, telecommunications, and medical industries.
