TLDR
In this paper, the curvature fringes occur as moire between two speckle slope patterns, and a good agreement between theory and experimental results is demonstrated by using holographic optical elements for the measurement of slope and curvature.Abstract:
This paper presents the use of holographic optical elements for the measurement of slope and curvature by video techniques. the curvature fringes occur as moire between two speckle slope patterns. A good agreement between theory and experimental results is demonstrated.read more

A systematic approach to TV holography
TL;DR: In this paper, the authors proposed an original scheme for the systematic treatment of TVH and to review the existing techniques according to it, and split the measurement process into four highly independent stages (illumination and observation geometry, temporal treatment, secondary-correlogram generation and fringe-pattern analysis) and establish a common notation to formulate the corresponding techniques.
