Abstract

A frequency domain heterodyne system for recording the amplitude and phase of diffuse photon density wave (DPDW) is described here. We demonstrated experimentally the possibility of tomographic image reconstruction using a pair of out-of-phase sources. Both iterative method (SIRT) and subspace technique (SVD) have been used to address the inverse problem. The image quality with respect to the number of iterations and regularization numbers is discussed. Further investigations including the relationship between several parameters (such as modulation frequency, the source pair separation and the number of source and detectors) and the image quality are also discussed.
