Experimental three-dimensional optical image reconstruction of heterogeneous turbid media from continuous-wave data

This paper demonstrates experimental three-dimensional (3D) image reconstruction of optically heterogeneous turbid media from near-infrared continuous-wave measurements. Successful reconstruction is achieved through a full 3D finite-element based, Newton-type reconstruction algorithm. Our experimental evidence shows that both absorption and scattering images of a 10x15 mm cylindrical object embedded in a 50x50 mm cylindrical background can be reconstructed using our algorithm.
