The measurement results of several optical improvement methods are compared with that of FT IR through the near infrared spectral measurement of water. The results show that both methods can effectively reject the inference of zero order light. But the orthogonal polarizing method does at the expense of the utilization ratio of light.

结果表明，两种方法均能有效地消除零级光的影响，但正交双偏振方法以牺牲光能利用率为代价，调制方法能够在不降低光能利用率的情况下提高AOTF分光系统的光谱分辨力和信噪比，并可以简化光路结构。
