The ASNT Local Iowa Section hosted a virtual guest speaker during their April 2025 meeting. Steven Fuller Jr. from NDT Systems presented to 17 professional and student attendees, seven of whom gathered in-person on Iowa State’s campus to enjoy complimentary pizza and soda while participating. Virtual attendees joined from Okoboji, Waterloo, IA, Springfield, IL, and as far away as Albuquerque, NM. The topic of the evening was Laser Shearography’s background, equipment, and applications. Steve began with manipulation of speckle patterns, excitation techniques, and indication formation and appearance. His talk finished with comparing sensitivity and false call rates, and several applications from aerospace and wind power industries.
