The ability of the spectral and polarization difference imaging (SPDI) technique to provide deep subsurface imaging in tissues was evaluated. A white Teflon strip positioned in the middle of the front surface breast chicken tissue layer was used as the target to be imaged. Another layer of breast chicken tissue was then positioned so that the object was sandwiched between the two breast tissue layers. Information on the image resolution was obtained as a function of the imaging depth. In another experiment using a 4-mm-diameter object, 700-1000 nm illumination, the maximum achievable imaging depth was found to be larger than 1-cm.
