Advances in the applications of holography for NDE
Abstract
Several recent applications of holographic interferometry to nondestructive testing are described and the basic methodology is discussed. Applications to the detection of cracks, particularly in ceramic materials, including a crack 50 μm in depth are given. A non-destructive method to quantify the gradual erosion of calcareous stones exposed to acid rain is presented.
