1. A method for measuring lung function in a living animal subject comprising;

  • (a) causing light of at least one wavelength, to contact a region of the lung within the subject;

    wherein the at least one wavelength includes an isobestic wavelength;

    (b) detecting a diffuse scattering pattern of light of each wavelength subsequent to its contact with the lung region;

    (c) measuring the diffuse scattering pattern detected in step (b) to provide scattering data and;

    (d) determining lung function information from the scattering data.
