项目摘要
We developed a high-speed linear detection time-domain optical coherence tomography (OCT) technique that detected a reflective grating-generated spatial optical delay in the reference arm using a line scan camera during probe-beam scanning. The image processing that involve a reference intensity removal, high pass fingering 1 D Hilbert transform and log scaling were accelerated by the GPU (graphics processing unit) with many stream processors, which realized highly parallel processing. A display rate of 94 frames per second for processed images with 500 lateral A-scans was achieved using an InGaAs line scan camera (512 pixels) operated at 47,000 lines/s. Our OCT system was successfully used to image the human finger in vivo with 93-dB sensitivity.
我们开发了一种高速线性检测时域光学相干断层扫描(OCT)技术,检测反射光栅产生的空间光学延迟在参考臂使用线扫描相机在探测光束扫描。图像处理包括参考亮度去除、高通指状一维希尔伯特变换和对数缩放等,由GPU(graphics processing unit)通过多个流处理器加速,实现了高度并行处理。使用以47,000线/秒操作的InGaAs线扫描相机(512像素)实现了对于具有500个横向A扫描的处理图像的每秒94帧的显示速率。我们的OCT系统已成功地用于成像的人的手指在体内与93 dB的灵敏度。
