  • Shearography and interferometry sensor with multidirectional dynamic phase shifting and method of inspection and measurement of vibration modes
    Patent number: 12265024
    Abstract: The present invention addresses to a multidirectional dynamic phase shifting interferometry (DPSI) shearography and interferometry sensor. The present invention uses a configuration with three fixed prisms, or a single fixed three-facet optical prism constructed so as to achieve the same effect as three prisms and thus simultaneously obtain three images with phase shifting. The present invention also encompasses a method of inspection and measurement of vibration modes using said sensor.

  • SHEAROGRAPHY SYSTEM FOR SUBSEA INSPECTIONS
    Publication number: 20230056235
    Abstract: The present invention proposes the use of the shearography technique in a system for the non-destructive inspection of composite material repairs applied to submerged metallic pipelines. The shearography system of the invention is characterized in that it comprises at least one vision and lighting module (VLM) (1), at least one fixation module (FM) (2), at least one excitation module (TEM) (3), at least one command and power module (CPM) (4), and a computer (5). The proposed system can be fixed to the repaired pipe by means of divers or ROVs, and the inspection control can be carried out entirely from the platform or surface support vessel.
