1. A system for use in tomographic imaging of a scattering medium, comprising : an imaging head including source fiber bundles in a first patterned array and receiver fiber bundles in a second patterned array, each fiber in said receiver fiber bundles not being identical with any of the source fiber bundles, wherein the source fiber bundles function as a plurality of energy sources in an illumination array , each energy source emitting a respective signal for imaging the scattering medium ; onto a different illumination area on a surface of said scattering target medium, wherein more than one of the plurality of energy sources emit emits their respective signals sequentially simultaneously and the respective signals are scattered by the scattering medium and emerge from the scattering medium ; , and wherein the plurality of receiver fiber bundles function as a plurality of detectors for detecting the respective signals that emerge from the scattering medium for use in measuring dynamic properties of the scattering medium in a time series of images using optical tomography.
