ABSTRACT:
A three-dimensional object imaging method is implemented on a computer for imaging an object. The three-dimensional object imaging method includes the steps of irradiating ultrasonic waves having two mutually different frequencies on the object which is to be imaged, measuring sound pressures of scattering waves from the object so as to obtain two acoustical holography images thereof, and obtaining a three-dimensional shape of the object based on a phase error between the two acoustical holography images.
