Digital image correlation (DIC) is a non-contact, optical, full-field displacement measurement technique used to map deformations on a body under an applied load by tracking surface features. It is a widely used method in experimental mechanics, owed

In this study, coupon specimens of both poled and de-poled lead zirconate titanate (PZT) are examined under quasi-static and stress-wave loading conditions. Mode-I crack initiation and fracture behavior is examined using ultra high-speed imaging in c

We present the optical performance of a compact variable optical attenuator (VOA) developed at Photintech. The presented VOAs operation principle is based on the guided wave evanescent field manipulation. Access to the evanescent portion of the gui
