Abstract

This paper discusses on the analytical modeling of the speckle decorrelation noise in digital Fresnel holographic interferometry. The complex coherence factor between two images from two digitally reconstructed holograms at two different instants is analyzed. The modulus of the coherence factor is established and depends on the local surface deformation. The main influencing parameters of the holographic set-up are discussed. Experiments confirm the validity of the proposed modelling.
