A method is provided for visualizing, in real time, a signal emitted by a non-destructive testing device including a rigid body, a non-destructive testing sensor connected to the rigid body, and an augmented reality visualization device. The method includes: emitting and receiving the signal by way of the sensor; determining a cut-out of an occlusion inside the mechanical part; determining a signal visualization surface constructed from the paths of the signal; and visualizing a superimposed real view and holographic 3D representation of the mechanical part, of the non-destructive testing sensor, a holographic representation of the cut-out of the occlusion and of the signal visualization surface, which are superimposed on the real view.

To determine severity of stepwise cracking in a pressurized vessel, a computer system receives an image collection of an area of a circumferential wall of the vessel. The image collection includes images distributed across the area, and represent respective cracks on the wall within the area. From among the images, the computer system identifies subsets of images, each including images of adjacent cracks. For the at least two images in each subset, the computer system determines multiple distances, each between an end of an image in each subset and an end of each other image in a subset. Based on the determined multiple distances, the computer system determines a probability of a crack propagating through cracks in each subset. Based on the crack intensity path determined for each subset of the multiple subsets, the computer system determines an operation to be performed on the vessel.

A method and a device for high frequency acoustic spectrum imaging for an object over a field of view. A camera captures an image of the object. A raster with grids is created as an overlay on the captured image. A directional microphone detects high frequency acoustic waves emanating from the object. An acoustic data signal corresponding to the high frequency acoustic waves is generated by a microphone data processing unit. The coordinates of the focal point of the directional microphone on the grid of the raster is recorded and sent as a real-time feedback position signal to a processor for each measurement of the acoustic signal data. The processor plots a visual representation of the acoustic signal data mapping it to the corresponding coordinates on the raster and creates a high frequency acoustic spectrum image for the object by superimposing the raster on the captured image.

A plurality of ultrasonic flaw detection methods can be switched and executed by a simple operation. An ultrasonic flaw detection apparatus includes a switching circuit 3 for permitting an angle probe 1 and a normal probe 2 to be arbitrarily switched to a transmission unit T and a reception unit R of a flaw detector. The switching circuit 3 can select an angle flaw detection mode for transmitting and receiving an ultrasonic beam only by the angle probe, an SPOD mode for transmitting the ultrasonic beam by the angle probe and receiving a diffracted wave by the normal probe and a flaw detection mode executed by a combination of angle flaw detection mode.

Methods of probing a material under investigation using an ultrasound beam. Echolocation data is generated using a multi-dimensional transform capable of using phase and magnitude information to distinguish echoes resulting from ultrasound beam components produced using different ultrasound transducers. Since the multi-dimensional transform does not depend on using receive or transmit beam lines, a multi-dimensional area can be imaged using a single ultrasound transmission. In some embodiments, this ability increases image frame rate and reduces the amount of ultrasound energy required to generate an image.
