Ultrasonic phased array detection system and method based on raw data
TL;DR: In this paper, an ultrasonic phased array detection system and method based on raw data is presented. But, the method requires no downsampling in the process of processing the ultrasonic echo signal from the to-be-measured object, and thus imaging and storage are carried out.
Patent
Ultrasonic defect detection qualitative system and qualitative method
TL;DR: An ultrasonic defect detection qualitative system and qualitative method that are implemented based on an ultrasonic phased array P-scan imaging device is presented in this paper, where the traditional ultrasonic detection equivalent method can be implemented and the structural defect like an object solder joint defect can be evaluated qualitatively byusing the P scanning imaging technique.

Scan detection method and device for sector scan imaging of ultrasonic phased array
TL;DR: In this article, a scan detection method and device for sector scan imaging of an ultrasonic phased array is presented. But the method comprises steps as follows: step one, coordinate transformation: polar coordinate data of multiple sampling points in a scan region is subjected to coordinate transformation, and rectangular coordinate data for each sampling point of a corresponding pixel point on an imaging coordinate system is obtained and stored; step two, interpolation on scan lines after coordinate transformation; four echo signal sampling points closest to a to-be-interpolated point are found by judging the linear position relation between the

Reflector morphological extraction system based on sound field characteristics and extraction method thereof
TL;DR: In this article, a reflector morphological extraction system based on sound field characteristics and an extraction method thereof is presented, where an ultrasonic wave is projected to a reflecting reflector, and ultrasonic echoes that are formed by reflecting the ultrasonic waves by the reflector at different receiving angles and different depths are reflected.
Patent
Nature determination system and nature determination method for ultrasonically detected defect
TL;DR: In this article, a nature determination system and nature determination method for an ultrasonically detected defect, the system and method being implemented on the basis of an ultrasonic phased array P-scanning imaging apparatus.
