AVGUR 2.1 COMPUTERIZED ULTRASONIC INSPECTION SYSTEM WITH COHERENT DATA-PROCESSING

The Avgur 2.1 computerized ultrasonic inspection system with coherent data processing is designed for the arbitration hazard assessment of d efects. Coherent processing offers fundamentally new ultrasonic inspec tion capabilities. It can be used to obtain high-resolution defect ima ges, to determine their characteristics and coordinates, and to make w ell-substantiated judgments of the type of defect (planar or volume). The results of testing of the Avgur 2.1 system in the reconstruction o f images of both synthetic and real defects are reported. The authors have endeavored to present the material in a form accessible to a broa d range of specialists.
