Which range of structures contributes to light scattering in a continuous random media, such as biological tissue? In this Letter, we present a model to study the structural length-scale sensitivity of scattering in continuous random media under the Born approximation. The scattering coefficient , backscattering coefficient , anisotropy factor , and reduced scattering coefficient as well as the shape of the spatial reflectance profile are calculated under this model. For media with a biologically relevant Henyey–Greenstein phase function with at wavelength , we report that is sensitive to structural length-scales from 46.9 nm to 2.07 μm (i.e., to ), is sensitive from 26.7 to 320 nm (i.e., to ), and the spatial reflectance profile is sensitive from 30.8 nm to 2.71 μm (i.e., to ).
