Surface effect measurement of a small scattering object in highly scattering medium by use of diffuse photon-pairs density wave

Abstract

We present a novel approach to measure the surface effect of a small scattering object in a highly scattering medium by using the amplitude and phase signal of diffuse photon-pairs density wave (DPPDW). The results demonstrate that DPPDW has high sensitivity for resolving the surface effect of a small object. Imaging in highly scattering media with the developed DPPDW method can potentially increase the spatial resolution of small scattering inclusions.keywords：surface effect, scattering medium, diffuse photon, photon-pairs, DPPDW
