| 摘 要： | 本文从理论上研究了ＯＣＴ系统的纵深剖析能力，结果表明ＯＣＴ系统具有很强的背景抑制能力．背景能量的影响随偏移量增大按指数规律急剧下降，同时还受到高频余弦调制，因而有极强的纵深剖析能力．本文的结论对实际应用中如何选择适当光源及定性理解与定量分析ＯＣＴ系统对未知结构的测量结果具有重要意义．

| Abstract: | Optical sectioning property of the optical low-coherence tomography(OCT)system has been analyzed theoretically. It has shown that the out-of-focus information is detected much less strongly. The derived formula showed that the contribution of the backgrounds is cosinoidally modulated and decreases exponentially with the displacement. So it has a strong optical sectioning effect. This research will be a help to Choose a moderate optical source in experiments. It is also a great help to qualitatively understand and quantitatively analyze the measurements of the unknown structure obtained by the OCT system. |
