In this work, we propose a novel dispersion compensation method that enables real-time compressive sensing (CS) spectral domain optical coherence tomography (SD OCT) image reconstruction. We show that dispersion compensation can be incorporated into CS SD OCT by multiplying the dispersion-correcting terms by the undersampled spectral data before CS reconstruction. High-quality SD OCT imaging with dispersion compensation was demonstrated at a speed in excess of 70 frames per s using 40% of the spectral measurements required by the well-known Shannon/Nyquist theory. The data processing and image display were performed on a conventional workstation having three graphics processing units.
在这项工作中，我们提出了一种新颖的色散补偿方法，该方法能够实现实时压缩感知（CS）光谱域光学相干断层扫描（SD OCT）图像重建。我们表明，通过在CS重建之前将色散校正项与欠采样光谱数据相乘，可将色散补偿纳入CS SD OCT。利用著名的香农/奈奎斯特理论所需光谱测量值的40%，以超过每秒70帧的速度展示了具有色散补偿的高质量SD OCT成像。数据处理和图像显示在配备三个图形处理单元的传统工作站上进行。
