OpTeC sponsors a colloquium throughout the academic year. This is a forum where a wide range of optical science and engineering topics are discussed at a level that can be understood by a broad spectrum of optics students, staff, and faculty. The primary purposes are to train students to give effective scientific talks and to promote cross-disciplinary interactions of students, staff, faculty, and local industry employees. Speakers include MSU students, staff, and faculty, and visitors from external universities, research labs, and companies.
Join our colloquium held during academic semesters on Thursday at 4:10 pm.
Dr. Stephen Schultz, Brigham Young University, will present
DYNAMIC MEASUREMENT OF SOFT BODY ARMOR USING OPTICAL FIBER SENSING
April 14, 2022
The dynamics of ballistic impact in soft body armor are measured using a single optical fiber. The sensor system consists of an optical fiber with a strain sensor embedded into a silicone mat. The silicone mat is placed between the Kevlar shoot pack and the backing material. The friction between the optical fiber and the materials is used to determine the position of the back face deformation as a function of time. The measurements are collected at a repetition rate of 100 kHz. The measurements have been performed with ballistic gel and high-speed imaging to characterize the system. The system was also characterized on 30 shots at the U.S. Army Aberdeen Test Center (ATC) Light Armor Range Complex (LARC) in Aberdeen, MD.
Stephen M. Schultz received B.S. and M.S. degrees in electrical engineering from Brigham Young University, Provo, UT, in 1992 and 1994. He received a Ph.D. in electrical engineering from the Georgia Institute of Technology, Atlanta, GA, in 1999. Dr. Schultz worked at Raytheon Missile Systems from 1999 to 2001. He began teaching at Brigham Young University in 2002 and is currently a Full Professor with research interests in optical fiber devices, emphasizing optical fiber-based sensors. He has authored or coauthored over 100 publications and holds ten patents.
