• Determine the speed of sound and the attenuation of ultrasonic signals in polyacrylate
• Localize defects
• Investigate aberrations resulting from acoustic shadows and ground returns
• Analyze frequency-dependent resolving power
• Display manual B-images.
Both the 1 MHz and 4 MHz transducers are required for studying resolution.
