Amplitude scans are carried out from different sides of the sample. The echo signals imaged in the recorded A-Scan images are examined and analysed. Keywords:...
Demonstration of the difference between the spectrum of a pulse and the spectra of periodic signals using the simple model of multiple reflection at a plate
Investigation of the formation and propagation of longitudinal and shear acoustic waves in solids based upon the ultrasonic transmission through a plane parallel plate at different angles of incidence
Demonstration of the basics of the B-scan method by recording the ultrasonic cross-sectional image of a simple test object “by hand” using an ultrasonic echoscope
Characterization of the sound fields of two ultrasonic probes of different frequencies by scanning reflection and transmission with a hydrophone (near field length, focus zone, axial resolution power)
