DEVELOPMENTS IN LASER ULTRASOUND SYSTEMS Laser ultrasound is a noncontact technique that uses a laser generator and a laser detector for nondestructive testing, characterization of materials, and measuring material thickness. In this issue, we briefly summarize three new patents focused on laser ultrasound systems. US 7,784,348 B2 ARTICULATED ROBOT FOR LASER ULTRASONIC INSPECTION (Marc Dubois, Thomas E. Drake, Jr., Kenneth Yawn, and Mark Osterkamp) This patent describes a laser ultrasonic nondestructive evaluation (NDE) system for inspecting complex materials. The ultrasound inspection head that gener- ates and detects a laser beam and collects phase modulated light scattered by a material is attached to an articulated robot that can inspect the material, previ- ously inaccessible to gantry robots. The scattered light collected is representative of the mechanical responses of the part and hence provides information about the internal structure. It is claimed that the system is adaptable toward wider and more complex environments as well as integrated components such as interior of an aircraft fuselage. US 10,539,538 B2 LASER ULTRASOUND SYSTEM AND METHOD FOR INSPECTION OF A CONTOURED STRUCTURE (Morteza Safai and Gary E. Georgeson) This patent describes a low-power fiber- based laser ultrasound system for NDE and quality certification of an array of nanoscopic structures having a prede- termined directional orientation. High- emissivity coatings are applied to the structure for better coupling of laser ultrasound. The incident laser energy is directed in a direction defined by the array orientation, and a pulsed laser beam is scanned across the structure to detect the reflected ultrasonic waves. The reflected waves are used to determine whether the structure meets a predeter- mined threshold. US 8,054,470 B2 METHOD AND APPARATUS FOR SPECTROSCOPIC CHARACTERIZATION OF SAMPLES USING A LASER-ULTRASOUND SYSTEM (Peter W. Lorraine, Thomas E. Drake, Jr., John B. Deaton, Jr., Marc Dubois, and Robert Filkins) This patent describes a spectroscopic analysis of a material using a laser ultra- sound system. The technique relies on measuring amplitude displacement of the material surface excited with a gener- ation laser that relates to the material’s thermoelastic expansion properties. The ultrasonic displacement is directly proportional to the optical penetration depth, which is inversely proportional to the material’s optical absorption prop- erties. The patent further claims that by varying the generation laser beam optical wavelength, an absorption band of the material can be observed over the wave- length range.

AMERICAN NATIONAL DRAFT STANDARDS PROJECT INITIATION ANSI procedures require notification by ANSI- accredited standards developers of the initiation and scope of activities expected to result in new or revised American National Standards. The following is a list of proposed actions and new standards that have been received recently from accredited standards developers. To view information about additional standards for which a project initiation notification has been submitted, and to search approved American National Standards, please visit ansi.org, which is a database of standards information. Note that this database is not exhaustive. BSR/ASNT CP-106-202x, Nondestructive Testing – Qualification and Certification of Personnel. This is an identical national adoption of ISO 9712:2012 and revision of ANSI/ASNT CP-106 (ISO 9712-2012)-2018. This standard specifies requirements for principles for the qualification and certification of personnel who perform industrial nondestructive testing (NDT). BSR/AWS C3.5M/C3.5-202x, Specification for Induction Brazing. This is a revision of ANSI/ AWS C3.5M/C3.5-2016-AMD1. This specification provides the minimum fabrication, equipment, and process procedure requirements, as well as inspection requirements for the induction brazing of steels, copper, copper alloys, and heat- and corrosion-resistant alloys and other materials that can be adequately induction brazed (the induction brazing of aluminum alloys is addressed in AWS C3.7M/C3.7, Specification for Aluminum Brazing). This specification provides criteria for classifying induction-brazed joints based on loading and the consequences of failure and quality- assurance criteria defining the limits of accept- ability in each class. The specification defines acceptable induction brazing equipment, materials, and procedures, as well as the required inspection for each class of joint. BSR/ASNT CP-105-202x, Standard Topical Outlines for Qualification of Nondestructive Testing Personnel. This is a revision of ANSI/ ASNT CP-105-2020. An essential element in the effectiveness of nondestructive testing (NDT) is the qualification of the personnel who are responsible for and who perform NDT. Formal training is an important and necessary element in acquiring the skills necessary to effectively perform nondestructive tests. The American Society for Nondestructive Testing Inc. (ASNT) has, therefore, undertaken the preparation and publication of this standard, which specifies the body of knowledge to be used as part of a training program for qualifying and certifying NDT personnel. BSR/ASNT CP-189-202x, Qualification and Certification of Nondestructive Testing Personnel. This is a revision of ANSI/ASNT CP-189-2020. This standard applies to personnel whose specific tasks or jobs require appropriate knowledge of the technical principles under- lying nondestructive testing (NDT) methods for which they have responsibilities within the scope of their employment. These specific tasks or jobs include, but are not limited to, performing, specifying, reviewing, monitoring, supervising, and evaluating NDT work.
