Acoustic wave research

Applications in medical field
(Associate Professor Masahiro Ohno’s research laboratory, Department of Life and Environmental Sciences, Faculty of Engineering, Chiba Institute of Technology)

Sugawara nano pulse lights are used in research to visualize acoustic wavefronts in various phenomena attributable to sound waves and ultrasound in the 10 kHz to 100 kHz band for applications in medicine and other fields.

Observations and research on ultrasound behavior
(Ultrasonic Wave Physics laboratory, Kansai University)

Sugawara nano pulse lights are used in conjunction with the Schlieren method to observe and research the behavior of ultrasonic waves—waves undetectable by the human ear or eye. Educational videos based on these efforts show the fundamental characteristics (diffraction and reflection) as wave motions.

Applications related to non-destructive inspection and medical equipment
(Associate Professor Hirotaka Yanagida, Professor Yasutaka Tamura’s laboratory, Informatics, Faculty of Engineering, Yamagata University)

Sugawara nano pulse lights are used with the Schlieren method to record (on video) and better understand the diffusion behavior in liquids of ultrasonic oscillations with a velocity of 1,500 m/s and amplitude of 0.2 to 2 mm for application to non-destructive inspection and medical equipment.
