Mechanical scan methods

Principle
The fundamental principles concerning the generation of ultrasonic B-scans (brightness scans) are demonstrated with the aid of a simple test object. The image quality characteristics, such as the zone of focus, resolving power, and artefacts, are explained.

Tasks

1. Determine the sound velocity of water and acrylic glass with the aid of the B-scan and the known dimensions of the test block.
   
2. Study any artefacts that occur.
   
3. Compare the resolution and zone of focus of 1 MHz and 2 MHz ultrasonic transducers.
