Abstract :
Numerical dispersion compensation for both standard and full-range Fourier-domain optical coherence tomography (FD-OCT) on the graphics processing unit (GPU) architecture has been implemented. The data acquisition, processing and image display were performed on a multi-thread, CPU-GPU heterogeneous computing system. The real-time ultra-high-resolution full-range complex-conjugate-free FD-OCT imaging was demonstrated at 68.4 frame/s with a frame size of 1024 (lateral) by 2048 (axial) pixels.
