1. A system for generating data for use in diagnosing the condition of surface tissue of a patient, comprising:

  • first means for scanning the surface tissue of a patient and for generating simultaneously n different signals from the light reflected from each incremental area of the surface tissue, each different signal being directly related to the reflectance of light of a different wavelength range from said incremental area, n being an integer not less than 2;

    second means for providing a preselected number of derived signals from the n signals, associated with each incremental area, each derived signal being a function of at least two of said n signals; and

    output means including at least means responsive to said derived signals for providing output data, indicative of the surface tissue condition.
