Capture, the driving force behind Eddyfi Technologies’ Gekko® and Mantis™ portable instruments as well as the Panther™ 2 industrial solution, is the pinnacle software for phased array ultrasonic testing and total focusing method. Constantly pushing non-destructive testing boundaries, Capture software version 4.1 introduces advanced capabilities, enabling operators to be the best inspector they can be.

Phase Coherence Imaging (PCI) Phase coherence imaging is a technique based on evaluating the coherence between signals detected by all the elements of a phased array ultrasonic testing probe like the Full Matrix Capture (FMC), sparse FMC, or Plane Wave Imaging (PWI) techniques.

PCI imaging, a non-amplitude based technique, uses phase information rather than amplitude for detection and focuses on diffraction echoes instead of specular ones. The intensity of a PCI image varies with the indication type. Omnidirectional sources like porosities, tip diffractions, and slag exhibit high intensity, while reflectors with directional dependence like front surface, backwall, delamination, and Lack of Fusion (LoF) show low-value phase coherence. PCI aids in detecting volumetric defects and identifying crack tip diffracted signals for improved sizing; learn more about PCI in this blog.
