1. A method of determining, in vivo, one or more characteristics of a sub-surface tissue or fluid, through a diffusely scattering overlying tissue, comprising steps of:

  • (a) supplying incident light at an entry region on a surface of the overlying tissue;

    (b) collecting light scattered within the overlying tissue, from a collection region on the surface, the collection region being spaced from the entry region; and

    (c) detecting, in the collected light, one or more Raman features, spectrally related to the incident light, which originate from the sub-surface tissue.
