SAFT-UT Utilities: Guide to SAFT-UT Principles and Conventions

摘要

This guide, the Guide to SAFT-UT (Synthetic Aperture Focusing Technique-Ultrasonic Testing), Principles and Conventions, is intended to provide the user with an overall background for practical implementation of SAFT-UT and the associated software utilities. It is not intended to exhaustively cover each related item, but rather to supply information from theory and experience that will assist the serious user in exploiting the robust nature of the SAFT technology. Chapter 1 gives an introductory overview from a historical perspective, emphasizing the need to maintain data integrity throughout the SAFT-UT imaging process. Chapter 2 includes a theoretical description of the Three SAFT-UT configurations currently being supported (single transducer pulse-echo, TSAFT, and TSAFT-2). A general description of the software tools is given in Chapter 3. It describes the major utilities and the general use of each one. Chapter 4 deals with the system resolution and sampling demands of SAFT-UT. A discussion of the strengths and limitations of the SAFT technique is provided in Chapter 5. The scanning conventions assumed throughout the implementation of the SAFT-UT utilities are detailed in Chapter 6. Chapter 7 lists an exhaustive supply of references for the user desiring to investigate the SAFT technology further. 26 refs., 19 figs. (ERA citation 13:003443)
