1. An apparatus for recording the optical responses of biological tissue, comprising in combination:

  • a. wavelength-tunable light generation means for rapidly generating high-brightness multiple wavelengths of light within a chosen range of wavelengths;

    b. fiber-optic means for collecting the light generated from said light generation means and for directing the light into a small volume of the biological tissue under investigation;

    c. detection means for receiving and for rapidly detecting light; and

    d. fiber-optic means for collecting the light emitted and scattered from the biological tissue and for directing the emitted and scattered light into said detection means, said means for collecting the generated light and said fiber-optic means for collecting the emitted and scattered light being disposed in a substantially parallel manner in the proximity of one another and in contact with the biological tissue, whereby light emitted, transmitted and scattered by the biological tissue is measured.
