Summary form only given. We are interested in the ability to image through turbid media using frequency-domain measurements together with tomographic reconstruction. Frequency-domain measurements through turbid media are performed by measuring the amplitude and phase of an amplitude-modulated optical source. From the measured amplitude and phase, information on both the absorption and scattering coefficients may be obtained. The propagation of the light through the turbid medium can be considered to be a highly damped diffusive wave called a photon density wave. Our particular interest is in the use of frequency-domain imaging in situations where absorption is not negligible, such as for underwater imaging and imaging through tissue at wavelengths near 1.3 /spl mu/m.
