Research output: Contribution to journalArticleResearchpeer-review


In digital speckle correlation interferometry, the discrete dynamic resolution of the recording determines the degree of accuracy in deriving the deformation related phase. In this letter, limiting relationships between truncation errors, conditions of saturation, self-interference levels and fringe contrast factors are established in relation with the constraints of this factor.
