At 8:00 a.m. on Wednesday, 20 November, Tsuchin Philip Chu, Ph.D., of Southern Illinois University will deliver the Lester/Mehl Honor Lecture, titled “Tiny Random Speckles: Why They Matter,” in Ballroom A-B.
The lecture will be about laser speckles and their potential use as an NDT technique. Chu’s research on this topic began with his dissertation, and his talk will share the various applications of the technique he has utilized in his nearly 30-year career working with it.
“Hopefully [attendees] will get some ideas on how to use these methods for NDT, because these are not traditional NDT methods,” Chu said. He noted that use of these speckles is more common in the field of mechanics. “It’s a potential for NDT, but not mainstream right now.”
Chu is a professor of the Department of Mechanical Engineering and Energy Processes at Southern Illinois University Carbondale (SIUC). He is also the director of the Engineering Science Ph.D. program in the College of Engineering at SIUC. This is not the first time that Chu has been recognized by ASNT for his expertise and involvement in the Society: he is an ASNT Fellow (class of 2019) and received the ASNT Mentoring Award in 2014, an ASNT Faculty Grant Award in 2012, 2017, and 2019, and an ASNT Fellowship Grant in 2010 and 2019.
This is the first year that the Lester/Mehl Honor Lecture will be delivered as one recognition. The Lester Honor Lecture and Mehl Honor Lecture were separate recognitions, given every other year, until 2018. The Lester/Mehl Honor Lecture is established in memory of the outstanding contributions to ASNT and the NDT industry by Horace H. Lester and Robert F. Mehl. Lester wrote numerous published articles, fostered techniques, and did seminal work in ASNT committees, and Mehl was the first person to use radium for gamma radiography.
