  • speckle metrology

Refers to the variety of techniques that use the interference pattern produced by laser light diffusely reflected by an object. There are two basic techniques: direct laser photography, used when there are correlations between the speckle patterns of the two images under study; and speckle interferometry, used when fluctuations in correlation between the images' patterns produce fringes, regardless of the translation between the correlated portions.
