Abstract
A method and a device for nondestructively detecting an elasticity of a viscoelastic medium are provided. The method includes: driving an ultrasonic transducer probe with a low-frequency vibration by a vibrator so as to produce an elastic wave in the viscoelastic medium; producing an ultrasonic wave by the ultrasonic transducer probe, and transmitting the ultrasonic wave to the viscoelastic medium; collecting an ultrasonic echo when the elastic wave is propagated in the viscoelastic medium and the ultrasonic transducer probe stops or almost stops vibrating; calculating an elastic parameter of the viscoelastic medium according to the collected ultrasonic echo.
