22 February 2017 High-speed complete OCT signal processing solution
Author Affiliations +
Optical coherence tomography (OCT) imaging systems can now produce MB=s to GB=s data streams. We present a complete solution for signal acquisition up to 4 GS/s and on-board field programmable gate array (FPGA) OCT processing matching the high acquisition speed. On-board OCT signal processing virtually eliminates the downstream signal processing and data throughput bottleneck. Complex filtering allows for windowing and dispersion compensation. Data is zero-padded when the number of samples is not a power of 2. The Fast Fourier Transform (FFT) engine can match the maximum acquisition speed when performing 4096-point FFTs. Output data can be linear amplitude or logarithmic and represented on several floating-point or integer precisions. This hardware solution comes with dedicated software and software development kit.
