NCPTT’s Curtis Deselles, a graduate student in the Masters of Heritage Resources program at Northwestern State University of Louisiana, is developing a handheld metal tester using eddy current technology. NCPTT has funded the study of eddy currents for the study of gilded bronze at the Freer Gallery in 1999. Deselles is taking the technology to new heights by writing software that makes the system operation on a handheld and may lead to easy identification of metals in the field.
