Abstract

We report on the software design of an ultra-parallel ultra-high speed spectral domain optical coherence tomography (SD-OCT) system. In our system, optical de-multiplexers divide an interferogram into 320 light every 18.7 GHz frequency, instead of a refractive grating for spectroscopy so far used in conventional SD-OCT. These optical elements enable to get rid of a re-sampling process and contribute to reduce the load of computing. The fast Fourier transform (FFT) is performed by field-programmable gate array (FPGA) and real-time 3D OCT images are created on graphics processing unit (GPU). Our system achieves a real-time 3D OCT image display (4D display) with an A-scan, B-scan, and volume rate of 10 MHz, 4 kHz, and 12 volumes per second, respectively.
