Witrynatissue produces a diffuse-photon density wave (DDPW) that propagates outward from the source. 9 The am-plitude and phase of this DPDW depend on the absorp-tion and the scattering coefficients within the turbid medium. In uniform turbid media the DPDW from a point source at r s detected at position r d has the form U. 0. s. r. d, r. s, vd M ... Witrynaof diffuse photon-density waves in tissues depend on the optical properties of the tissue. When ... Imaging of spherical objects by diffuse photon-density waves has been investigated, first for objects embedded in a homogeneous medium (Boas et al 1993) and later for objects in a layered medium of spherical symmetry (Yao et al … WitrynaDiffuse photon density waves are proposed for use in characterizing diffuse media, similar to the use of electro-magnetic waves to characterize reflection from materials. To this end basic expressions for the reflection and transmission coefficients at interfaces are put forward. Effects such as the existence of modes analogous with Brewster … our child\u0027s behavior阅读理解
