1. A tomography system, comprising: a plurality of lasers of a first group, each laser of the first group for generating light of a distinct wavelength within a first wavelength band; apparatus for applying the light from lasers of the first group to mammalian tissue at laser-specific locations; apparatus for collecting light from the mammalian tissue at a plurality of reception points; apparatus for separating light received from the apparatus for collecting light according to a wavelength of the received light; apparatus for generating a path attenuation signal encoding received light amplitude information for each reception point at each wavelength corresponding to each laser of the plurality of lasers; and image construction apparatus for receiving the path attenuation signal and for reconstructing a tomographic image of the mammalian tissue.
