Abstract

Objects hidden in human tissue can be imaged using optical diffusion tomography. Here we demonstrate that high modulation frequencies lead to better spatial resolution for the measured data in comparison to the data with low modulation frequencies, whereas the converse is true for postprocessed images. Furthermore, based on the turbid-media version of diffraction tomography, we can also characterize the hidden object using low-frequency (or DC) data measured in a planar geometry.
