Abstract
An ultrasonic tester includes an ultrasonic sensor that applies ultrasound to a test object; a casing that holds the ultrasonic sensor immersed in a contact medium that allows the ultrasound to propagate therethrough, the casing including a test object-facing opening Further, there is circuitry configured to, when the test object-facing opening of the casing is passing an opening of the test object in a test direction of the test object, control a moving speed of the casing such that a region of contact between the test object and the contact medium entering the opening of the test object is kept within the opening of the test object.

An ultrasonic device, comprising:
- an ultrasonic sensor that applies ultrasound to a test object;
- a casing that holds the ultrasonic sensor to be immersed in a contact medium that allows the ultrasound to propagate therethrough, the casing including a test object-facing opening;
- and
- circuitry configured to, when the test object-facing opening of the casing is passing an opening of the test object in a test direction of the test object, control a moving speed of the casing such that a region of contact between the test object and the contact medium entering the opening of the test object is kept within the opening of the test object.
A method, comprising:
- sensing a test object through an opening of a casing, the casing holding a contact medium;
- and
- controlling a moving speed of the casing such that a region of contact between the test object and the contact medium entering an opening of the test object is kept within the opening of the test object.
