1. An apparatus for obtaining spectral information and quantifying the physical properties of a sample comprising:

  • a light source for providing light;

    a high-efficiency fiber optic switch means, in communication with said light source through a single fiber optic strand, said high-efficiency fiber optic switch means directing said light alternatively along at least two channels, said channels comprising at least one reference channel and at least one sample channel;

    a sampling means in communication with said sample channel for providing an interface between said light and said sample;

    a mode scrambler;

    a fiber optic means selected from the group consisting of a high-efficiency fiber optic switch and an optical coupler, in communication with said sample channels and said reference channels for directing said light alternatively from said reference and sample channels to said mode scrambler;

    a wavelength discrimination device for separating said light into component wavelengths and providing spectral information for the determination of the physical properties of said sample.
