Variable angle ultrasonic transducers evaluated by the photoelastic visualisation method (TM-PHYS-032)

A photoelastic technique which allows the propagation of ultrasound in glass models to be visualised, has been used to study the performance of variable angle ultrasonic transducers. In the photoelastic visualisation apparatus of Fig 1, a strohoscopic light source emits short flashes of light which pass through a system of...
