Published in 2021 at "Optics express"

DOI: 10.1364/oe.423391

Abstract: This paper presents analytical modelling for describing the speckle noise decorrelation in phase data from two- or multiple-wavelength digital holography. A novel expression for the modulus of the coherence factor is proposed for the case… read more here.
