N2 - 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 μs, backscattering coefficientμb, anisotropy factor g, and reduced scattering coefficient μ*s 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 g ∼ 0.93 at wavelength λ = 633 nm, we report that μ*s is sensitive to structural length-scales from 46.9 nm to 2.07 μm (i.e., λ/13 to 3λ), μb is sensitive from 26.7 to 320 nm (i.e., λ/24 to λ/2), and the spatial reflectance profile is sensitive from 30.8 nm to 2.71 μm (i.e., λ/21 to 4λ).
