AB  - The useful imaging range in spectral domain optical coherence tomography (SD-OCT) 
      is often limited by the depth dependent sensitivity fall-off. Processing SD-OCT 
      data with the non-uniform fast Fourier transform (NFFT) can improve the 
      sensitivity fall-off at maximum depth by greater than 5dB concurrently with a 30 
      fold decrease in processing time compared to the fast Fourier transform with 
      cubic spline interpolation method. NFFT can also improve local signal to noise 
      ratio (SNR) and reduce image artifacts introduced in post-processing. Combined 
      with parallel processing, NFFT is shown to have the ability to process up to 90k 
      A-lines per second. High-speed SD-OCT imaging is demonstrated at camera-limited 
      100 frames per second on an ex-vivo squid eye.
