其轴向分辨率由光源带宽和探测光束的聚焦条件共同决定。

Axial resolution in optical coherence tomography (OCT) imaging is determined by the coherence length of light source and the beam-focusing condition.

分析比较不同发射口面分布下的电磁波的传播规律，得出满足聚焦条件的一种口面分布。

The optimum distribution, which could let the EM wave focus inside the Fresnel zone, is given as well.
