ABSTRACT:
A method for measuring the physical characteristics of an object through the use of an ultrasonic wave, which comprises the steps of transmitting an ultrasonic pulse to the object, receiving a reflected wave from the object, analyzing the spectrum of a parameter representing the strength of the reflected wave and obtaining a center frequency of the spectrum to measure the physical characteristics of the object. The center frequency is used as a function of distance or time to obtain its differential or difference coefficient, or a computation similar to that for an X-ray computer tomography is carried out, thereby to obtaining an attenuation slope and other data to be used as the physical characteristics of the object.
