The calculations of the FFT (fast Fourier
transform) were accelerated by the
GPU (Graphic Processing Unit) with
many stream processors, which realized
highly parallel processing.
The display rate of OCT images (2048
1000 lateral A-scans)
was at 27.9 fps using a line scan CCD
camera operated at 27.9 kHz.
