1. A Raman spectroscopy system comprising:

  • a plurality of light transmission channels;

    a time-division multiplexing device for distributing, in a time multiplexed manner, at least one portion of Raman Stokes radiation scattered from a biological tissue sample to each of the plurality of light transmission channels, wherein the Raman Stokes radiation is formed as a result of light impinging on the biological tissue sample;

    a light detector for detecting the distributed portion of the Raman Stokes radiation passed by each of said transmission channels, further wherein each of the transmission channels comprises a filter to select a specific wavelength range for each channel;

    an analyzing processor for processing a signal from the light detector to detect at least one particular condition of the biological tissue sample.
