Journal ArticleDOI
Validity conditions for the radiative transfer equation
Luis Martı́-López,Jorge Bouza-Domínguez,Jeremy C. Hebden,Simon R. Arridge,R.A. Martínez-Celorio +4 more
TL;DR: In this paper, the authors compare the radiative transfer equation for media with constant refractive index and media with spatially varying refractive indices and obtain approximate conditions under which the former equation is accurate for modeling light propagation in scattering media.
Journal ArticleDOI
Temporal difference method for processing dynamic speckle patterns
TL;DR: A temporal difference method for processing dynamic speckle images is proposed and a variant of the method that allows measuring the area of an activity zone surrounded by a static region is tested in digital simulations.
Journal ArticleDOI
Measurement of out-of-plane deformation by combination of speckle photography and speckle shearing interferometry
TL;DR: In this paper, the derivative of out-of-plane deformation in presence of large in-plane rigid body displacement (RBD) was measured by a combination of Electronic Speckle-Shearing Pattern Interferometry (ESSPI) and speckle photography.
Journal ArticleDOI
An investigation of the ability of modified radiative transfer equations to accommodate laws of geometrical optics
TL;DR: In this article, the radiative transfer equation (RTE) and its approximations are used for describing light propagation in biological tissues, and the RTE is valid for media with constant refractive indices, an assumption that does not hold in many practical situations.
Journal ArticleDOI
Extension of the displacement measurement range for electronic speckle-shearing pattern interferometry using carrier fringes and a temporal-phase-unwrapping method
TL;DR: In this paper, a technique for increasing the displacement measurement range in electronic speckle-shearing pattern interferometry is proposed based on the introduction of carrier fringes and the use of a temporal-phase-unwrapping method to obtain larger measuring ranges of out-of-plane displacements of an object without sign ambiguities.
