The invention uses the eddy current array probe coils in two separate ways to produce a first set of detection channels and a second set of lift-off measurement channels without the need to add coils dedicated to the lift-off measurement operation. Another aspect of the invention provides an improved calibration process which combines the detection and lift-off measurement channel calibration on a simple calibration block including a reference defect without the need of a pre-defined lift-off condition. | 2021-01-14 |
20210010976 | SNAPSHOT PHOTOACOUSTIC PHOTOGRAPHY USING AN ERGODIC RELAY - A photoacoustic imaging system is disclosed that includes an ergodic relay coupled optically to a light source configured to produce a light pulse and further coupled acoustically to a transducer. The ergodic relay is further configured to direct at least two PA signals to the transducer. Each of the at least two PA signals are produced at different positions within the field of view of the object to be imaged in response to illumination by a single light pulse. The transducer detects each of the at least two PA signals after each of at least two delays that correspond to the position at which each PA signal was produced. | 2021-01-14 |
20210010977 | ACOUSTIC WAVE SUPERSCATTERING - A device can be configured to cause the superscattering of acoustic waves and/or to enable incident angle-dependent scattering. The acoustic superscattering device can include a body that has an outer peripheral surface. One or more resonators can be defined in the body. The one or more resonators can open to the outer peripheral surface of the body. When there are a plurality of resonators, the resonators are not in communication with each other within the body. The acoustic superscattering device can be configured to cause the superscattering of a target acoustic wave impinging upon the body. | 2021-01-14 |
