我们展示了高速，高灵敏度，高分辨率的光学成像的基础上使用快速调谐的波长扫描激光的光频域干涉。我们推导并实验表明，频域测距提供了一个优越的上级的信号-噪声比相比，传统的时域测距中使用的光学相干断层扫描。一个高的灵敏度为-110 dB，获得了6 mW的源，在轴向分辨率为13.5妈妈和A线速率为15.7 kHz，代表超过一个数量级的改善与以前的OCT和干涉成像方法相比。(C)2003年美国光学学会。
We demonstrate high-speed, high-sensitivity, high-resolution optical imaging based on optical frequency-domain interferometry using a rapidly-tuned wavelength-swept laser. We derive and show experimentally that frequency-domain ranging provides a superior signal-to-noise ratio compared with conventional time-domain ranging as used in optical coherence tomography. A high sensitivity of - 110 dB was obtained with a 6 mW source at an axial resolution of 13.5 mum and an A-line rate of 15.7 kHz, representing more than an order-of-magnitude improvement compared with previous OCT and interferometric imaging methods.
