相干体技术是通过道与道之间的非相似性，以显示和突出与地质异常有关的地震数据的横向变化。
The coherence technique is to make use of in comparability channel to channel, displaying and highlighting seismic data transversal changes related to geological anomalies.
采用了动态聚焦的方法，能使整个扫描过程中，焦点一直落在相干门内，保证横向分辨率是不变的。
With the method of dynamic focus, the focus point can be located in the coherence gate during the whole depth scanning. So, the lateral resolution keeps constant.
当光学相干层析技术用于眼底视网膜成像时，其横向分辨率受限与人眼的像差。
When optical coherence tomography (OCT) is used for human retina imaging, its transverse resolution is limited by the aberrations of human eyes.
