Abstract
This invention relates to an apparatus and method for performing bidirectional Raman spectroscopy of a sample, preferably a diffusely scattering sample, in which two excitation light sources are employed to illuminate the sample from two opposite directions to excite Raman scattering signal from the sample. The Raman scattering signal which transmits through the sample are collected by two optical devices each positioned on the opposite side of the sample to obtain two transmission Raman spectra of the sample, which enables the accurate determination of the composition of the whole sample.
