论文摘要
我们通过高速摄像头和高速相机从光学获得的干涉图中实时演示了扫描源光学相干断层扫描。在空间上相对于波长进行了空间重新缩放，以补偿离散菲涅耳转换固有的视野扩张。全息图是从16位，1024 by-1024像素干涉图的输入流计算的，使用数码相机记录的每秒512帧记录。所有计算均通过单精度浮点数复合物值阵列（每个正交32位）上的NVIDIA TITAN XP图形卡执行。它允许以100亿素/s的持续计算1024-BY-1024-BY-256-VOVOXEL量，从用户选择的位置实时显示三个垂直切割，每秒最多38帧。
We demonstrate swept-source optical coherence tomography in real-time by high throughput digital Fresnel hologram rendering from optically-acquired interferograms with a high-speed camera. The interferogram stream is spatially rescaled with respect to wavelength to compensate for field-of-view dilation inherent to discrete Fresnel transformation. Holograms are calculated from an input stream of 16-bit, 1024-by-1024-pixel interferograms recorded at up to 512 frames per second with a digital camera. All calculations are performed by a NVIDIA TITAN Xp graphics card on single-precision floating-point complex-valued arrays (32-bit per quadrature). It allows sustained computation of 1024-by-1024-by-256-voxel volumes at 10 billion voxel/s, from which three perpendicular cuts are displayed in real-time at user-selected locations, up to 38 frames per second.
