光被物质非弹性散射的现象被称为拉曼光谱，以1928年首次实验观察到的钱德拉塞卡拉·文卡塔·拉曼爵士的名字命名[1]。由于在106-1012个入射光子中只有一个光子是非弹性散射或拉曼散射的，所以花了一段时间才研制出具有足够高的光强以有效地激发拉曼的激光器和用于测量仍然很弱的拉曼光的非常灵敏的探测器。发展拉曼仪器的另一个重要步骤是有效地抑制非常强烈的弹性散射光，即瑞利光，通过双或三重单色器或滤光器[2]。
The phenomenon of inelastic scattering of light by matter is referred as Raman spectroscopy named after Sir Chandrasekhara Venkata Raman who first observed it experimentally in 1928 [1]. Because only one photon out of 106-1012 incident photons is inelastically or Raman scattered, it took some time until lasers with high enough light intensities for efficient Raman excitation and very sensitive detectors for measuring the still low intensity Raman light were developed. Another important step in advancing Raman instrumentation was the efficient rejection of the very intense elastic scattered light, known as Rayleigh light, through a double or triple monochromator or filters [2].
