Visualization of Ultrasonic Waves in a Solid by Stroboscopic Photoelasticity and Image Processing Techniques

A Quantitative Evaluation of Elastic Wave in Solid by Stroboscopic Photoelasticity

“…Since the relationship between the principal stress components is known in the case of ultrasonic longitudinal wave and shear wave as shown in Figure 2, the ultrasonic wave stress (sound pressure) can be measured and evaluated at any point by measuring the intensity of the brightness on the synthesized picture [13][14][15][16].…”

Ray-Modeling for Computer Simulation of Ultrasonic Testing

“…The ultrasonic shear wave visualized by the photoelastic ultrasonic visualized system [4] is shown in Fig. l(a).…”

“…Ultrasonic visualization methods have been applied for studying wave propagation and reflection [1][2][3][4]. Computer simulation analysis of wave propagation have also been conducted.…”

Visualization of ultrasonic wave field by stroboscopic polarization selective imaging

“…Acoustic evanescent waves have been successfully visualized by a stroboscopic photoelastic method with high spatial resolution [20]. The photoelastic method was also elaborated to quantitatively evaluate the acoustic waves by modulating two orthogonal polarizers [21,22]. But it was subject to a low imaging speed.…”
