Example Embodiment
[0019] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0020] theoretical analysis
[0021] Such as figure 1 Shown is a schematic diagram of the ultrasonic incident principle. Set the acoustic impedance of the air and the measured object as Z 1 With Z 2 ; T 12 Is the ultrasonic transmittance from the air to the measured object, T 21 Is the ultrasonic transmittance of the measured object to the air; T 121 Indicates the ultrasonic transmittance from the air to the measured object and then to the air, T 12121 Indicates the ultrasonic transmittance from air to the measured object, then to the air, then to the measured object, and finally to the air, R 12 Is the reflectivity between the air and the measured object, R 21 Is the reflectivity of the measured...
