The light scattering is the main reason to degrade the imaging resolution of optical tomography. In order to improve the imaging resolution, polarization and scattering angle differential technique was developed to suppress the effect of scattering in turbid medium. An explicit theory for the technique was presented and a transillumination imaging system under the technique was set up. Using this system, the feasibility of this technique was demonstrated through a serial of experimental measurements in model phantom and higher resolution was obtained than that maintained by conventional method. The technique shows promise in getting the high resolution imaging in conjunction with other optical tomography methods.
