Abstract
An ultrasonic wave inspection device includes: a transmitter that outputs ultrasonic waves toward an inspection object; a receiver that receives at least first ultrasonic waves passed through the inspection object, among the ultrasonic waves output from the transmitter; a member that regulates a second propagation path, the second propagation path being a portion of propagation paths through which the output ultrasonic waves reach the receiver, and the second propagation path being different from a first propagation path through which the first ultrasonic waves reach the receiver; and a signal controller that extracts ultrasonic waves of a predetermined time segment from at least the first ultrasonic waves, the predetermined time segment starting from a time when the first ultrasonic waves is received.
Claims19
An ultrasonic wave inspection device comprising:
- a transmitter that outputs ultrasonic waves toward an inspection object;
- a receiver that receives at least first ultrasonic waves passed through the inspection object, among the ultrasonic waves output from the transmitter;
- a member that regulates a second propagation path, the second propagation path being a portion of propagation paths through which the output ultrasonic waves reach the receiver, and the second propagation path being different from a first propagation path through which the first ultrasonic waves reach the receiver;
- and
- a signal controller that extracts ultrasonic waves of a predetermined time segment from at least the first ultrasonic waves, the predetermined time segment starting from a time when the first ultrasonic waves is received.
An ultrasonic wave inspection device comprising:
- a transmitter that has a first surface and outputs ultrasonic waves toward an inspection object;
- a receiver that has a second surface facing the first surface and receives the ultrasonic waves output from the transmitter;
- a member that is arranged between the transmitter and the receiver and faces a partial region of the first surface and a partial region of the second surface;
- and
- a guide that guides the inspection object and makes at least an end portion of a peripheral portion of the inspection object overlap with the member when viewed from an arrangement direction in which the transmitter and the receiver are arranged.
