在本文中，我们证明主从（MS）干涉测量方法可以显着简化相干复兴扫频源光学相干断层扫描（OCT）技术的实践。以前的相干恢复技术的实现需要大量资源用于色散补偿和数据重采样。 MS 方法对非线性调谐、干涉仪色散以及激光腔引起的色散的总体耐受性使 MS 非常适合相干性复兴的实践。此外，MS 方法在显示比数据数字采样确定的轴向范围图像更短的轴向范围图像时允许增强多功能性。这立即提高了高速显示横截面图像的速度，而无需额外的硬件，例如图形处理单元或现场可编程门阵列。健康人类志愿者眼前节的图像证明了相干性恢复机制的长轴范围。 (C) 2016年美国光学学会
In this paper, we demonstrate that the master slave (MS) interferometry method can significantly simplify the practice of coherence revival swept source optical coherence tomography (OCT) technique. Previous implementations of the coherence revival technique required considerable resources on dispersion compensation and data resampling. The total tolerance of the MS method to nonlinear tuning, to dispersion in the interferometer and to dispersion due to the laser cavity, makes the MS ideally suited to the practice of coherence revival. In addition, enhanced versatility is allowed by the MS method in displaying shorter axial range images than that determined by the digital sampling of the data. This brings an immediate improvement in the speed of displaying cross-sectional images at high rates without the need of extra hardware such as graphics processing units or field programmable gate arrays. The long axial range of the coherence revival regime is proven with images of the anterior segment of healthy human volunteers. (C) 2016 Optical Society of America
