We present a full-range, complex, spectral-domain optical-coherence-tomography (SD-OCT) system that is based on a double-beam scanning approach. The sample beams of two identical SD-OCT setups are combined collinearly by a bulk optic beam splitter before illuminating the object. The required phase shift for the complex signal reconstruction comes from the phase difference between both interferometers. Because of the double-beam scanning approach, our system is completely insensitive to sample motion. To demonstrate the performance of our setup, we present images of the human optic nerve head in vivo and of a human tooth.
我们展示了一种基于双光束扫描方法的全谱、复杂、光谱域光相干断层扫描（SD-OCT）系统。在照明物体之前，两个相同的 SD-OCT 设备的样品光束通过一个块状光学分束器共线组合。用于复杂信号重建的所需相移来自两个干涉仪之间的相位差。由于双光束扫描方法，我们的系统对样品运动完全不敏感。为了演示我们的设置的性能，我们展示了人眼视神经头和人牙的活体图像。
