ABSTRACT:
In a system for irradiating an ultrasonic beam and imaging the insides of plate-shaped and layer-shaped samples, by using the difference between the sound velocities of a liquid medium and a sample from an ultrasonic transducer to the surface of the sample, the focusing condition is arithmetically operated from the distance between the transducer and the imaging surface which is obtained from the surface echo, and a focal point is set to an arbitrary surface in the sample, thereby correcting a phenomenon such that the focal point of the ultrasonic beam focused into the sample non-linearly moves. Thus, even if the sample is distorted, curved, or inclined, the surface can be imaged at a high resolution and a finer imaging picture can be obtained.
