Microsecond holographic interferometer for fracture studies
Abstract
A detailed description of the operation of each component that makes up a double-pulsed, ruby-laser, holographic interferometer is presented. Some results obtained from the dynamic measurement of three-dimensional surface deformation related to fracture initiation and propagation in 6061 aluminum are reported.
