ATS-GPU-OCT 4.0 is an optional signal processing library that uses ATS-GPU-BASE (sold separately) to acquire data and provide out-of-the-box OCT imaging with very high speed floating point FFT, windowing, dispersion compensation, zero padding and log kernels. Benchmarks have shown A-line rates up to 950,000 for 4096 point FFT and 1.9 Million for 2048 point FFT.
ATS-GPU-OCT library is callable from virtually any programming environment (C/C++, C#, LabVIEW®, MATLAB®, Python). Since these programming environments cannot call CUDA functions directly, the internal structure of ATS-GPU-OCT 4.0 is fixed and cannot be modified by the user. Users are still allowed to download their own window function, dispersion compensation function, set zero-padding and select output data format.
