Technical Abstract: Although the Raman effect was discovered in 1928 by C.V. Raman it received little attention as a spectroscopic method until lasers (high intensity monochromatic light sources) were employed as sources. Recent developments to include improved detectors and filters, techniques to suppress of fluorescence and efficient computer processing have made it an extremely popular technique. These more recent developments have given rise to two basic techniques, NIR-FT-Raman and dispersive Raman using CCD cameras. These techniques can be employed in three forms for microspectroscopy and imaging: indirect point and line-scanning and direct global Raman imaging. Raman microspectroscopy and imaging complement that of infrared and together have essentially formed the field known as chemical microscopy.
